Abstract: | AbstractRecent developments in the thermochemical treatment of steels at MADI, Moscow are presented. These technologies combine nitriding with other methods of surface modification, e.g. thermal diffusion and laser alloying, plasma treatment, galvanic and slurry metallisation, and oxidation. By regulating the parameters of each process, it is possible to control the structure of the surface at the micro- and nanoscales, to form coatings and/or surface layers on various carbon and alloyed steels with tailored properties (hardness, wear and corrosion resistance, etc.) for machine parts used in various working conditions. |
