Dzieki naniesieniu warstwy chro¬ mu, oraz wytworzeniu azotków i weglików w warstwie powierzchniowej stali uzyskuje ona wieksza twardosc, niz sam material zaharto¬ wany. Obecne badania wykazaly, ze mozna zwiekszyc twardosc stali przez osadzenie na jej powierzchni, lub wprowadzenie do jej war¬ stwy powierzchniowej zwiazków fosforu, siar¬ ki, azotu, boru i innych pierwiastków, które tworza krysztaly mieszane zmieniajace struk¬ ture stali, nadajac jej zadane wlasciwosci. Do tego utwardzania uzywa sie roztworów odpo- *) Wlasciciel patentu oswiadczyl, ze twór¬ cami wynalazku isa mgr Jan Latoszek i inz.Bohdan Kucharzewski. wiednich soli, którymi sie dziala na stal w ciagu czasu od kilku do kilkunastu minut, a nastepnie plucze sie woda.Sposób wedlug wynalazku polega na zanu¬ rzeniu utwardzanych narzedzi do roztworu soli o temperaturze 90—120°C na przeciag kil¬ ku lub kilkunastu minut w celu nasycenia ich warstwy powierzchniowej zwiazkami fos¬ foru, azotu, boru itd., po czym plucze sie je woda w temperaturze 40—60°C. W przypadku narzedzi bardzo twardych, np. sluzacych do ciecia szkla, plucze sie je w temperaturze 0 ¦— 20°C, po uprzedniej obróbce w roztworach soli.Sposób ten wymaga bardzo prostego urza¬ dzenia i malej ilosci energii, a równoczesnie chroni narzedzia przed korozja i nie wplywa na zmiane wymiarów narzedzi lub innych wy¬ robów stalowych. PL2 J Published on January 25, 1957 OF THE POLISH PEOPLE'S REPUBLIC PATENT DESCRIPTION No.38493 KI. 18- c, 3/25 Zaklady Mechaniczne "Ursus"; y ^ <£ Panstwowe Przedsiebiorstwo Wyodrebowane *) Ursus near Warsaw, Poland Method of surface hardening of cutting tools made of carbon or alloy slal The patent is valid from November 3, 1954 in order to obtain the tools and Other steel objects of greater hardness after hardening are subjected to various types of surface treatment, such as: chrome plating, plating, etc. Due to the application of a layer of chrome, and the production of nitrides and carbides in the surface layer of the steel, it obtains greater hardness than the hardened material itself.Current studies have shown that the hardness of steel can be increased by depositing on its surface, or by introducing phosphorus, sulfur, nitrogen, boron and other elements into its surface layer, which form mixed crystals that change the structure of the steel, giving it the desired properties. For this hardening solutions are used. *) The owner of the patent stated that the creators invented zku isa mgr Jan Latoszek and engineer Bohdan Kucharzewski. The method according to the invention consists in immersing the hardened tools into a salt solution at a temperature of 90-120 ° C for a period of several or a dozen or so minutes. minutes to saturate their surface layer with compounds of phosphorus, nitrogen, boron, etc., and then rinsing them with water at 40-60 ° C. For very hard tools, such as those used to cut glass, they are rinsed at 0 ° C -20 ° C after being treated with saline solutions. This method requires a very simple device and little energy, while protecting the tools from corrosion and does not alter the dimensions of tools or other steel products. PL
