Abstract
Nickel-based alloy coatings were obtained on carbon steel (steel 3) samples by means of high-velocity pulsed plasma jet spraying of PG-10N-01 and PGAN-33 commercial powders, followed by electron beam fusion of the coating and substrate. The coated samples were studied by methods of X-ray diffraction, scanning electron microscopy, and electron-beam microprobe (energy-dispersive X-ray spectroscopy) and tested for hardness, friction wear, corrosion resistance, and adhesion. It was found that the electron beam processing leads to an almost tenfold increase in the friction wear resistance, a threefold growth in microhardness (relative to that of the substrate), and a significant increase in the resistance to corrosion in acid media. The observed increase in the working characteristics is related to changes in the phase composition, grain structure refinement, and redistribution of alloy components in the substrate and film and a decrease in porosity of the coating material.
