Description

Oppfinnelsen angår en konstruksjonsdel i drivverk og som er utsatt for innvirkning fra aggressive medier, særlig skovler i turbindrivverk, hvilken del består av et indre, grunnmateriale og et materialsjikt som omhyller grunnmaterialet. The invention relates to a structural part in a drive train which is exposed to the impact of aggressive media, particularly blades in a turbine drive train, which part consists of an inner base material and a layer of material which envelops the base material.

Det er kjent på egnet måte å belegge overflaten av konstruksjonsdeler som er utsatt for høye temperaturer, aggressive medier og lignende. Til belegging av konstruksjonsdeler for trubinstråle-drivverk s.om er utsatt for temperaturer opp til 600°C, særlig skovler, er det kjent å påføre belegget retnings-bestemt og brenne det inn i en ovn. Denne fremgangsmåte er • mindre egnet når det kreves en ekstrem overflatekvalitet på kompliserte konstruksjonsdeler. Det er også kjent plasmasprøyt-ing og diffusjonsbehandling som imidlertid påvirker grunnmaterialet. It is known in a suitable way to coat the surface of structural parts which are exposed to high temperatures, aggressive media and the like. For the coating of structural parts for turbin jet drives which are exposed to temperatures of up to 600°C, especially vanes, it is known to apply the coating in a directionally determined manner and burn it in an oven. This method is • less suitable when an extreme surface quality is required on complicated construction parts. Plasma spraying and diffusion treatment are also known which, however, affect the base material.

Til grunn for oppfinnelsen ligger den oppgave å skaffe et belegg for kompliserte konstruksjonsdeler til turbindrivverk, hvilket har en ekstremt god overf1atekvalitet. The invention is based on the task of providing a coating for complicated construction parts for turbine drives, which has an extremely good surface quality.

Denne oppgave er ifølge oppfinnelsen løst ved at materialsjiktet er blitt påført' på grunnmaterialet ved påsprutning etter den såkalte " Sputter ingmetode". According to the invention, this task is solved by the material layer being applied to the base material by spraying according to the so-called "sputtering method".

Fortrinnsvis består materialsjiktet av SiO^. Det kan imidlertid også anvendes et annet oksyd såsom f .eks. Al^Q^eller In^O^. Også et karbid såsom f.eks. Cr^C^kan finne an-vendelse. Preferably, the material layer consists of SiO 2 . However, another oxide can also be used, such as e.g. Al^Q^or In^O^. Also a carbide such as e.g. Cr^C^ may find use.

Fordelene ved løsningen ifølge oppfinnelsen er tall-rike: a) En ytterst glatt overflate med en ruhetsgrad Ra mot'0. b) Et gunstig forhold mellom arbeidsstykke, særlig skovletykkeisen og beleggets tykkelse. c) Anvendelsen åv forskjellige grunnmaterialer er mulig. d) Bindefastheten under svingningsbelastninger er absolutt «sikre.t..' e) Sjiktet er motstandsdyktig overfor korrosjon og erosjon. f) En sprekkdannelse i overflaten av grunnmaterialet vil ikke bli ført videre. •g) Beskyttelsessjiktet er tett og fører ikke til at korrosive medier angriper grunnmaterialet. The advantages of the solution according to the invention are numerous: a) An extremely smooth surface with a degree of roughness Ra against'0. b) A favorable relationship between the workpiece, especially the blade thickness, and the thickness of the coating. c) The use of different base materials is possible. d) The bond strength under swing loads is absolutely "safe.t..' e) The layer is resistant to corrosion and erosion. f) A crack formation in the surface of the base material will not be carried forward. •g) The protective layer is tight and does not cause corrosive media to attack the base material.

h) Temperaturbestandigheten er ytterst høy.h) The temperature resistance is extremely high.

i) Påføringen av flere typer av elementer er muligi) The application of several types of elements is possible

med den samme fremgangsmåte.with the same procedure.

j) Fastheten medhensyn til svingningsdempende virk-ning ved lave temperaturer økes. j) The firmness is increased due to vibration-damping effect at low temperatures.

k) ■ Sputteringmetoden er rasjonelt gjennomførbar. k) ■ The sputtering method is reasonably feasible.

Sputteringmetoden bygger på atomær hhv. molekylær ned-brytning av et materiale fra en formdel ved hjelp av en energi som går ut fra en katode, idet anoden danner den del som skal belegges. Ved hjelp av en høyfrekvent vekselstrøm som går utfra 'en katode, blir atomene løst fra formdelen (target) og beveger seg med stor hastighet mot prøven eller delen, på hvilken dfit sålodes bygger seg opp et sjikt, (indirekte metode). The sputtering method is based on atomic or molecular breakdown of a material from a mold part by means of an energy emanating from a cathode, the anode forming the part to be coated. With the aid of a high-frequency alternating current emanating from a cathode, the atoms are released from the mold part (target) and move at high speed towards the sample or part, on which a layer is thus built up (indirect method).

i vakuum befinner seg flere kranser av kompressorstator-eller rotorskovler 1 for høytrykkskompressoren i et turbindrivverk, hvis overflate skal belegges ifølge oppfinnelsen, opphengt på egnet måte. Det materiale som skal brytes ned og avleires på skovlene 1, er lagret som formdelen 2 på midten av beholderen 3 som omslutter vakuumet. Mellom formdelen 2 og skovlene er anordnet anodegitteret 4. Ved hjelp av høyfrekvent vekselstrøm utløses en energistrøm fra katoden til formdelen 2, ved hjelp av hvilken atomer utløses fra formdelen og påføres drivverk-skovlene- som et sjikt (fig. 1). in vacuum, there are several rings of compressor stator or rotor blades 1 for the high-pressure compressor in a turbine drive, the surface of which is to be coated according to the invention, suspended in a suitable manner. The material to be broken down and deposited on the vanes 1 is stored as the mold part 2 in the middle of the container 3 which encloses the vacuum. Between the mold part 2 and the vanes, the anode grid 4 is arranged. Using high-frequency alternating current, an energy flow is released from the cathode to the mold part 2, with the help of which atoms are released from the mold part and applied to the drive vanes as a layer (fig. 1).

En på denne måte belagt skovle er vist på fig. 2. Grunnlegemet la er på alle sider omsluttet av et ytterst glatt tett sjikt lb av S i 0 2 • Sjiktet er ytterst tynt og slik dimen- sjonert at det hverken løsner ved de svingninger som skovlene utsettes for under drift eller at beleggets beskaffenhet påvirker drivverkets virkningsgrad, men tvert imot på grunn av sin uforandrede lukkethet begunstiger denne uavhengig av varig-heten av arbeidet. A vane coated in this way is shown in fig. 2. The basic body la is surrounded on all sides by an extremely smooth dense layer lb of S i 0 2 • The layer is extremely thin and dimensioned in such a way that it neither loosens due to the oscillations to which the vanes are exposed during operation nor that the nature of the coating affects the powertrain's efficiency, but on the contrary, because of its unchanged closure, it favors this regardless of the duration of the work.
