Conclusions

The self-fluxing alloys PN-KhN90S2R2 and PN-KhN80S3R3 sprayed by the plasma method increase the corrosion resistance of 40Kh and 3 steels at 773–1223°K in molten NaNO3-KNO3 by 4–10 times, in Na2SO4,-K2SO4 by 3–12 times, and in (NaPO3)n or (KPO3)n by 20–80 times. In NaCl-KCl the corrosion resistance of carbon steels and nickel-containing self-fluxing alloys is the same.
