摘要：
Microarc thermochemical treatment (MTCT) is suggested for intensification of diffusion saturation of the surface layer of steel articles. The hardened article is immersed into powdered mineral coal and heated by passed electric current. The main stages of the MTCT process are determined. The diffusion layer is shown to be accelerated by carburizing. High-hardness coatings are obtained due to simultaneous diffusion of carbon, chromium, molybdenum and boron.
