An effective way to effectively change the characteristics of electric arc coatings made from crushed materials can be achieved by creating high-quality surface balls in them due to the use of different methods. chemical-thermal treatment. Research was carried out on the development and testing of the concept of molding chemical dry coatings based on the combined process of electrode deposition with technological processing of pulsed ion nitriding. It has been shown that duplex (combined) technology, which combines electric arc filing and nitriding, allows one to obtain a significant effect on non-structural properties, increased hardness, heat transfer and wear resistance of the part-coating system with a reduced degree of deformation of the part. An assessment was made of the possibility of moving the electric arc coatings from martensitic steels (40Х13, 95Х18), ferrite (Sv-08G2S) and austenitic (Х18Н10Т, 12Х18Н10Т) classes. further processing of nitriding.
