The authors describe the plasma arc spraying of a corrosion-resistant chromium-nickel steel alloyed with boron and silicon onto a steel-3 and steel-40KH base and proceed to investigate the corrosion kinetics of the coating when acted upon by the corrosive forces of the molten chlorides, nitrates, sulfates, and phosphates of sodium and potassium. Their results indicate that the plasma-spray coatings increase the corrosion resistance of the two base steels to the nitrates by four to ten times, to the sulfates by three to twelve times, and to the phosphates by twenty to eighty times. The corrosion resistance to sodium and potassium chlorides remained the same.
