Description

[0001]Ovaj pronalazak odnosi se na lim koji obuhvata supstrat koji ima najmanje jednu površinu prevučenu metalnom prevlakom koja obuhvata Al i Mg, ostatak metalne prevlake koji je Zn, neizbežne nečistoće i eventualno jedan ili više dodatnih elemenata izabranih među Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni ili Bi, pri čemu je maseni sadržaj svakog dodatnog elementa u metalnoj prevlaci manji od 0,3%.
[0002]Galvanizovane metalne prevlake koje se u suštini sastoje od cinka i 0,1 do 0,4 mas.% aluminijuma tradicionalno se koriste za njihovu dobru zaštitu od korozije.
[0003]Ove metalne prevlake sada su izazvane naročito metalnim prevlakama koje sadrže cink, i dodatno magnezijum i aluminijum respektivno do 10mas.% i do 20mas.%.
[0004]Takve metalne prevlake ovde su zajednički označene kao cink- aluminijum- magnezijum prevlake ili ZnAIMg.
[0005]Dokumenti US 3,505,043 i EP 2 119 804 opisuju takve prevlake.
[0006]Dodatak magnezijuma značajno povećava otpornost na koroziju protiv crvene rđe ovih prevlaka, što omogućava smanjenje njijhove debljine ili povećanje garancije zaštite od korozije tokom vremena pri konstantnoj debljini.
[0007]Ovi limovi namenjeni su, na primer, za upotrebu u automobilskoj industriji, za električne uređaje ili u građevinarstvu.
[0008]Mogu biti dodati u premaze pre ili posle njihovog ađustiranja od strane korisnika iz ovih oblastima. Kada su premazani pre ađustiranja, nazivaju se "predlakirani" limovi, pri čemu su oni posebno namenjeni za upotrebu kod električnih uređaja i u građevinarstvu.
[0009]U slučaju predlakiranih limova, celokupan postupak proizvodnje limova implementiran je kod proizvođača čelika, čime se smanjuju troškovi i ograničenja povezana sa postupkom premazivanja kod korisnika.
[0010]Međutim, primećeno je da poznate metalne prevlake mogu biti sklone problemima delaminacije slojeva premaza, što dovodi do lokalne korozije lima.
[0011]Jedan predmet ovog pronalaska je da obezbedi prevučeni lim čija se otpornost na koroziju povećava kada je premazan.
[0012]U tu svrhu, ovaj pronalazak prvo se odnosi na lim prema patentnom zahtevu 1.
[0013]Lim takođe može da uključuje karakteristike iz patentnih zahteva 2 do 12, pojedinačno ili u kombinaciji.
[0014]Ovaj pronalazak takođe se odnosi na postupak prema patentnom zahtevu 13.
[0015]Postupak takođe može da obuhvata karakteristike iz patentnih zahteva 14 i 15, pojedinačno ili u kombinaciji.
[0016]Ovaj pronalazak sada će biti ilustrovan primerima datim samo indikativno, bez ograničenja, pozivajući se na pridružene slike u kojima: FIG. 1 je šematski prikaz preseka koji prikazuje strukturu lima prema ovom pronalasku nakon
premazivanja,
FIG. 2 do 4 su šematski prikazi koji ilustruju mikrostrukturu površine neobrađene metalne
prevlake lima sa FIG. 1,
FIG. 5 je dijagram koji prikazuje rezultate testova delaminacije obavljene na uzorku lima prema
ovom pronalasku i limova koji nisu prema ovom pronalasku, i
FIG. 6 je dijagram koji prikazuje krive gustine struje i potencijal korozije različitih faza.
[0017]Lim 1 sa FIG. 1 obuhvata supstrat 3 prekriven na svakoj od svoje dve površine 5 metalnom prevlakom 7, koja je sama prekrivena filmom 9,11 premaza.
[0018]Može se primetiti da relativne debljine supstrata 3 i različitih slojeva koji ga prekrivaju nisu ispoštovane na FIG. 1 kako bi se olakšao prikaz.
[0019]Prevlake 7 prisutne na obe površine 5 slične su i nadalje će detaljno biti opisana samo jedna. Alternativno (nije prikazano), samo jedna površina 5 ima prevlaku 7.
[0020]Prevlaka 7 uopšteno ima debljinu manju od ili jednaku 25 u.m i namenjena je da zaštiti supstrat 3 od korozije.
[0021]Prevlaka 7 obuhvata cink, aluminijum i magnezijum. Maseni sadržaj aluminijuma tAiu metalnoj prevlaci 7 je između 3,6 i 3,8%. Maseni sadržaj magnezijuma tMg u metalnoj prevlaci 7 je između 2,7 i 3,3%.
[0022]Poželjno, sadržaj magnezijuma tMg je između 2,9 i 3,1%.
[0023]Poželjno, maseni odnos AI/(AI+Mg) je veći od ili jednak 0,45, ili je čak veći od ili jednak 0,50, ili je čak veći od ili jednak 0,55.
[0024]Kao što je prikazano na FIG. 2 do4,prevlaka 7 ima posebnu mikrostrukturu sa lamelarnom matricom 13 ternarnog eutektika Zn/Al/MgZn2. Kao što se može videti na FIG. 3, lamelama matrica 13 formira zrna razdvojena spojevima 19.
[0025]U poželjnom obliku ovog pronalaska, ternarni eutektik čini celokupnu mikrostrukturu prevlake.
[0026]Interlamelarno rastojanje lamelarne matrice 13 može veoma da varira u okviru njenih zrna, naročito blizu struktura koje su opciono obuhvaćene ovom matricom, a čije će strukture sada da budu opisane.
[0027]Pored lamelarne matrice 13 pomenute gore, mikrostruktura, na površini i u poprečnom preseku, može da sadrži male količine Zn dendrita 15 i cvetove 17 binarnog eutektika Zn/MgZn2, koje nisu suviše štetne za poboljšanu otpornost na delaminaciju dobijenu prema ovom pronalasku.
[0028]Da bi se ovo postiglo, akumulisani površinski sadržaji Zn dendrita 15 i cvetova 17 binarnog eutektika Zn/MgZn2na spoljašnjoj površini 21 u sirovom stanju su ograničeni.
[0029]Poželjno, akumulisani površinski sadržaj Zn dendrita 15 na spoljašnjoj površini 21 u sirovom stanju je manji od 5,0%, ili čak 3,0%, ili čak 2,0%, ili čak 1,0%, a idealno je nula, dok je akumulisani površinski sadržaj cvetova 17 binarnog eutektika Zn/MgZn2na spoljašnjoj površini 21 u sirovom stanju manji od 15,0%, ili čak 10,0%, ili čak 5,0%, ili čak 3,0%, a idealno je nula.
[0030]Mikrostruktura može takođe da uključuje dendrite binarnog eutektika Zn/AI ili MgZn2ostrvca u vrlo malim količinama jer ove strukture snažno pogoršavaju otpornost na delaminaciju limova prevučenih prema ovom pronalasku.
[0031]U svakom slučaju, akumulisani površinski sadržaj dendrita binarnog eutektika Zn/AI na spoljašnjoj površini 21 u sirovom stanju je manji od 1,0% i akumulisani površinski sadržaj MgZn2ostrvaca na spoljašnjoj površini 21 u sirovom stanju je manji od 1,0%, a akumulisani sadržaji su poželjno nula.
[0032]Slično, respektivni akumulisani sadržaji u poprečnom preseku, dendrita binarnog eutektika Zn/AI i MgZn2ostrvaca poželjno su nula.
[0033]Tako, uopšteno, mikrostruktura obuhvata lamelarnu matricu 13 ternarnog eutektika i eventualno Zn dendrite 15, cvetove 17 binarnog eutektika Zn/MgZn2, dendrite binarnog eutektika Zn/AI i MgZn2ostrvca. Međutim, u zavisnosti od prisustva dodatnih opcionih elemenata pomenutih u nastavku, mikrostruktura može takođe da obuhvata male količine drugih struktura obuhvaćenih u lamelarnoj matrici 13 ternarnog eutektika.
[0034]Akumulisani površinski sadržaji za svaku strukturu se, na primer, mere uzimanjem najmanje 30 okvira sa X1000 uvećanjem spoljašnje površine 21 u sirovom stanju (tj. bez poliranja ali poželjno odmašćene organskim rastvaračem) korišćenjem skenirajućeg elektronskog mikroskopa.
[0035]Za svaki od ovih okvira, izvade se konture strukture čiji sadržaj treba da se izmeri, a zatim se izračunava, na primer softverom AnalvSIS Docu 5.0 od Olvmpus Soft Imaging Solutions GmbH, stopa popunjenosti spoljašnje površine 21 strukturom koja je u pitanju. Stopa popunjenosti izračunava se kao akumulisani površinski sadržaj strukture koja je u pitanju.
[0036]Filmovi 9 i 11 premaza baziraju se, na primer, na polimerima. Ovi polimeri mogu biti poliestri ili halogenovani vinil polimeri kao što su plastizoli, PVDF.
[0037]Filmovi 9 i 11 obično su debljine između 1 i 200 nm.
[0038]Da bi se izradio lim 1, mogu se, na primer, izvesti sledeće faze.
[0039]Postrojenje koje se koristi može da obuhvata jednu liniju ili, na primer, dve različite linije radi respektivnog izvođenja metalnog prevlačenja i premazivanja. U slučaju kada se koriste dve različite linije, one mogu da se nalaze na istoj lokaciji ili na različitim lokacijama. U opisu koji sledi, kao varijanta primera razmatran je slučaj u kom su korišćene dve odvojene linije.
[0039]U prvoj liniji za nanošenje metalne prevlake 7 koristi se supstrat 3 dobijen, na primer, toplim valjanjem, a potom hladnim valjanjem. Supstrat 3 je u obliku trake koja prolazi kroz kadu radi taloženja prevlake 7 toplim potapanjem.
[0040]Kada je kada sa rastopljenim cinkom koja sadrži magnezijum i aluminijum. Kada takođe može da sadrži do 0,3mas.% dodatnih opcionih elemenata kao što su Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni ili Bi.
[0041]Ovi različiti dodatni elementi mogu da omoguće, između ostalog, poboljšanje žilavosti ili adhezije prevlaka 7 na supstratu 3. Stručnjak u ovoj oblasti kome je poznato njihovo dejstvo na karakteristike prevlaka 7 koristiće ih u funkciji željenog dodatnog cilja. Konačno, kada može da sadrži zaostale elemente koji potiču od napojnog ingota ili koji rezultuju iz prolaza supstrata 3 kroz kadu, kao što je železo u količini do 0,5mas.%, a uopšteno između 0,1 i 0,4mas.%.
[0042]Kada ima temperaturu Tb između 360°C i 480°C, poželjno između 420°C i 460 °C.
[0043]Na ulazu u kadu, supstrat 3 ima temperaturu uranjanja Ti takvu da je:
gde je Ti izraženo u stepenima Kelvina.
[0044]Takva temperatura uranjanja Ti omogućava da se dobije gore navedena mikrostruktura sa malo ili bez struktura obuhvaćenih u lamelarnoj matrici 13.
[0045]Uopšteno, ova temperatura Ti određuje se na lokaciji na osnovu meranja izvršenog nekoliko metara uzvodno od kade metodom sa pirometrom a potom primenom termičkog modela za izračunavanje temperature Ti.
[0046]Radi variranja Ti i zadovoljenja gore date jednačine, modifikuju se uslovi za hlađenje supstrata 3 uzvodno od kade. Ovo hlađenje može se postići uduvavanjem inertnog rashladnog gasa na dve površine 5 supstrata 3 pomoću rashladnih komora, čiji gasni pritisak može da se reguliše. Takođe je moguće da se podesi brzina pomeranja supstrata 3 u zoni hlađenja ili čak, na primer, temperatura supstrata 3 na ulazu u ovu zonu.
[0047]Nakon taloženja prevlaka 7, supstrat 3 se, na primer, obriše pomoću mlaznica za raspršivanje gasa na obe strane supstrata 3.
[0048]Zatim se omogući hlađenje prevlaka 7 na kontrolisan način kako bi očvrsnule.
[0049]Altrnativno, pranje se može izvesti radi uklanjanja prevlake 7 istaložene na površini 5 tako da samo jedna od površina 5 lima 1 na kraju bude prevučena prevlakom 7.
[0050]Kontrolisano hlađenje neke ili svake prevlake 7 obezbeđeno je brzinom poželjno većom od ili jednakoj 15°C/s između početka očvršćavanja (tj. kada temperatura prevlake 7 padne malo ispod temperature likvidusa) i kraja očvršćavanja (tj. kada prevlaka 7 dostigne temperaturu solidusa). Poželjnije, brzina očvršćavanja neke ili svake prevlake 7 između početka očvršćavanja i kraja očvršćavanja je veća od ili jednaka 20°C/s.
[0051]Tako tretirana traka zatim može da bude podvrgnuta takozvanoj fazi dresiranja kojom se omogućava otvrdnjavanje i daje se hrapavost koja olakšava njeno ađustiranje.
[0052]Traka može opciono da bude namotana pre nego što stigne do linije pred-lakiranja.
[0053]Spoljašnje površine 21 prevlaka 7 mogu da budu podvrgnute fazi odmašćivanja i opciono fazi tretiranja površine da bi se povećala adhezija premaza i otpornost na koroziju.
[0054]Opcione faze odmašćivanja i tretiranja površina mogu da uključuju druge podfaze kao što su ispiranje, sušenje.
[0055]Postupak premazivanja može se zatim izvesti, na primer, nanošenjem dva uzastopna sloja premaza, naime primarnog sloja a potom završnog sloja što je uopšteno slučaj kojim se postiže gornji film 9, ili nanošenjem jednog sloja premaza što je uopšteno slučaj kojim se postiže donji film 11. U nekim varijantama, drugi brojevi slojeva mogu da se koriste.
[0056]Nanošenje slojeva premaza može se izvoditi, na primer, valjcima nanosačima.
[0057]Svako nanošenje sloja premaza uopšteno je praćeno pečenjem u peći.
[0058]Tako dobijen lim 1 može se namotati ponovo pre sečenja, opciono ađustiran i sastavljen sa drugim limovima 1 ili drugim elementima od strane korisnika.
Testl
[0059]Uzorak lima 1 pripremi se prema ovom pronalasku i pripreme se uzorci limova koji nisu prema ovom pronalasku variranjem temperature uranjanja Ti, tAii tMg uzoraka. Odgovarajuće mikrostrukture analiziraju se radi određivanja postojećih struktura i njihovih akumulisanih površinskih sadržaja.
Test 2
[0060]Testovima delaminacije podvrgnuti su uzorak lima 1 prema ovom pronalasku i limovi koji nisu prema ovom pronalasku radi meranja njihove otpornosti na koroziju ispod premaza.
[0061]Preciznije, prevlake testiranih limova imaju debljinu od 8u.m.
[0062]Sastav prevlaka 7 limova 1 prema ovom pronalasku ima sadržaj tAiod 3,7% i sadržaj tMg od 3,0%. Kao što je naznačeno u apcisi na FIG. 5, ostali sastavi testiranih prevlaka imali su vrednosti tAiod 0,3 %, 1,5%, 6,0% i 11,0% i vrednosti tMg od 1,0%, 1,5%, 3,0 i 3,0%.
[0063]Mikrostruktura lima prema ovom pronalasku sastoji se jedino od ternarnog eutektika i dobija se uranjanjem u kadu sa prevlakom na temperaturi Tb = 460°C, pri čemu traka ima temperaturu Ti = 480°C.
[0064]Testovi korozije su u skladu sa standardom VDA 621-415 (10 ciklusa).
[0065]Preciznije, testirani limovi su fosfatirani, prevučeni slojem kataforeze i zagrebani do supstrata sečivom širokim lmm.
[0066]Maksimalne širine Ud delaminacije izmerene u mm nakon testova korozije za različite ispitivane limove date su na ordinati na FIG. 5.
[0067]Kao što se može videti, širine delaminacije optimalne su za lim prema ovom pronalasku.
[0068]Potpuno iznenađujuće, otkriveno je da se povećanjem akumulisanih sadržaja aluminijuma i magnezijuma iznad vrednosti ovog pronalaska, pogoršava otpornost na delaminaciju a, prema tome, na koroziju.
[0069]Sada, pronalazači veruju da je ova dobra otpornost na koroziju ispod premaza zbog određene mikrostrukture prevlaka 7 koja ograničava rizik od električnog spajanja između njihovih različitih struktura i lamelarne matrice 13.
[0070]Usled niskog prisustva struktura obuhvaćenih u lamelarnoj matrici 13, na spoljašnjoj površini 21 svake prevlake 7, ustvari je smanjen rizik od selektivnog rastvaranja ovih faza.
[0071]Na FIG. 6 prikazan je na apcisi potencijal korozije u odnosu na referentnu kalomelovu elektrodu zasićenu u KCI (SCE), a na ordinati gustina struje. Kriva 23 odgovara sastavu koji obuhvata 3,7mas.% Al i 3,0mas.% Mg, a preostali deo je Zn. Ova kriva predstavlja lamelarnu matricu 13.
[0072]FIG. 6 pokazuje da je rizik od korozivnog spajanja lamelarne matrice 13 veći kod strukture koja sadrži Al (kriva 25), Mg (kriva 27) i Zn (kriva 29).
[0073]Uopšteno, limovi 1 prema ovom pronalasku ne moraju biti stavljeni na tržište u obliku sa premazom ("predlakirani" limovi) i/ili mogu biti prevučeni najmanje slojem ulja.
