从理论上分析了金属腐蚀的原因及实质,论述了不同合金层具有不同的化学性质,指出非晶合金具有特殊的化学性质,这与它的结构有关。并且试验研究了具有这种特殊非晶结构的Ni-Mo-P合金层的耐蚀性。在大量实验的基础上,确定了获取三元合金镀层的工艺配方,即15～25g/L硫酸镍,15～20g/L次亚磷酸钠,3～5g/L钼酸钠,另外含少量的络合剂和稳定剂。经结构分析所得合金层为非晶态结构。腐蚀实验证明该镀层具有很好的耐有机溶剂及有机酸和盐的性质;有耐强碱和耐浓硫酸的特性。
The reasons and the essence of metal corrosion are theoretically analyzed. The different chemical properties of different alloy layers are discussed. It is pointed out that amorphous alloys have special chemical properties, which is related to its structure. The corrosion resistance of the Ni-Mo-P alloy layer with this special amorphous structure was experimentally studied. Based on a large number of experiments, the technological formula for obtaining the ternary alloy coating is determined, that is, 15 to 25g / L nickel sulfate, 15 to 20g / L sodium hypophosphite, 3 to 5g / L sodium molybdate, Complexing agents and stabilizers. The structure of the alloy layer obtained by the amorphous structure. Corrosion experiments show that the coating has a good resistance to organic solvents and organic acids and salt properties; resistance to alkali and resistance to concentrated sulfuric acid.
