The studies assess the possibility of increasing the corrosion resistance, wear resistance of the surface of steel St3 using the method of plasma surface modification. The addition of OK 84.78 electrode coating powder in mixtures containing NiCrBSi leads to the increase of surface hardness. It is shown that the higher the content of OK 84.78 coating powder in the modifying mixture, the higher the probability of occurrence of defects in the fused surface layer (cracks, pores, heterogeneity). Studies of corrosion processes in a 3% NaCl solution show that coatings containing alloyed elements Cr, Ni have a higher passivation in a corrosive environment. NiCrBSi + 20% OK 84.78 coating is considered to be high corrosion-resistant.
