The article presents the results of experimental studies of the surface properties of gas-thermal spray coatings of the rotor downhole drilling motors. Was analyzed the adhesion and corrosion resistance of coatings, obtained as a result of putting various powders on steel of various grades. It was established experimentally that the substrate material of the examined steels has almost no effect on the adhesion of the coating.

Abstract Thermal spray coatings are very effective in combating wear and corrosion in many applications. New thermal spray processes and coating compositions continue to be developed with concomitant improvements in the performance of the coatings and their use in new applications. Nonetheless, the thermal spray coatings are not without competition from other coating and overlay processes and materials. This brief review considers the microstructures and the wear and corrosion resistance of a number of alternative coatings to thermal spray coatings, including physical vapor deposition, chemical vapor deposition, electroplating, autocatalytic, and laser cladding.
