Abstract

The model of microstructure of thick (about 300 μm) plasma detonated Co-based coatings on steel substrates is suggested on the basis of experimental research. Computer simulation of temperature distribution in depth from the surface of coatings under plasma jet irradiation was done; and certain parameters for additional treatment by irradiation were proposed. The irradiation was carried out according to the design conditions. It was established that the roughness of the modified coatings decreased by 2 times, microhardness increased on the average by 25 %. There was established the evolution of the structure and phase composition of the coatings after irradiation, which caused the improvement of their strength.
