Abstract
The work was performed within the framework of the complex program of the NAS of Ukraine «Problems of life and safe operation of structures, constructions and machines», 2011–2020. The corrosion and tribocorrosion characteristics of plasma-powder and electric arc coatings on pipe steels in chloride-containing media with hydrogen sulfide and ammonia were studied. It was established that the corrosion resistance of the coatings applied by plasma-powder surfacing and electric arc spraying is improved with an increase in pH of the solution. It was shown that the coatings deposited by the plasma method with the powder of 08Kh17N35S3R alloy were the most resistant to corrosion and mechanical fracture in these media. It was established that electric arc coatings sprayed from the flux-cored wire 75Kh19RЗS2 reduce the corrosion current density of carbon steels in a hydrogen sulfide solution by 40 %. In the same medium on the surface of the coatings sulfide compounds are formed, which act as a solid lubricant during friction, facilitating a reduction in wear of the material by 40−42 %. The electric arc coatings produced by the flux-cored wire 75Kh19RЗS2 were proposed to be used to restore damaged surfaces of parts and protect them from corrosion and abrasive wear in the hydrogen sulfide media. 14 Ref., 5 Tables, 4 Figures.
