Description
Summary:The paper presents an overview on various surface hardening methods, with special attention towards chemical heat treatment (CHT). Development of several processes/technologies in this regard, is mentioned. For iron and steel (mainly steel 45) nitriding, carburizing, boriding and alloying with refractory metals (Ni, Mo, Ti, Nb, V, Cr, W) and Si with laser alloying are discussed. The possibility is demonstrated of increasing hardness to 2000 H, and the wear and heat resistance of carbon steels to a level typical for high-speed steels. The diffusion-condensation method is found to provide high wear and corrosion resistance for the surface with an improved fatigue limit. Development of mathematical models and software in creating equipment for CHT is described.
