This work is devoted to establishing the effect of High Velocity Oxygen-Fuel (HVOF) method for spraying coatings with vanadium carbide (VC) (as an alternative to galvanic chromium plating) on the wear resistance of obtained coatings in friction condi

We study the corrosion resistance of coatings obtained by submerged-arc built-up welding. The fused metal is obtained from Fe-based flux-core wires of the Kh10R4G2S grade. On the basis of the results of phase analysis, it was discovered that the fuse

We study electric-arc coatings of the Fe–Cr–C and Fe–Cr–B systems. It is shown that chromium content of 12 wt.% is insufficient to guarantee higher corrosion resistance of the coatings in neutral aqueous solutions (as compared with steels) ca
