Abstract

On carbon steel substrate, base coating of nickel-coated aluminium and intermediate coating of 50% Al2O3 + 50% Ni were prepared by means of oxyacetylene spray, and final coating of Al2O3 ~ MxOy was prepared by means of plasma spray. In the fluid consisting of 60% (mass) sulphuric acid with 60 % concentration, and 40% (mass) phosphoric ore powder, the Al2O3 ~ MxOy coating resistance to corrosion and wear, is 7.46 times as strong as 18 - 8 stainless steel and is 4.06 times as strong as 316L stainless steel.
