在碳钢母材上，用氧乙炔焰喷焊镍包铝合金粉末制取预涂层，喷焊50% Al₂O₃+50% Ni的复合粉末制取过渡层，用等离子喷焊Al₂O₃ - M_xO_y复合粉末制取最终涂层。在质量分数为60%的硫酸与磷矿粉组成的混合介质（质量比为6∶4）中运转，所获得涂层的抗腐抗磨能力为18-8不锈钢的7.46倍，为德产316L不锈钢的4.06倍。

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 ～ M_xO_y 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 ～ M_xO_y 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.
