【摘要】 探讨了在钢表面获得彩色化学镀镍层的方法,分析了各种工艺因素对色彩的影响,同时对彩色镀层的耐磨、耐蚀性能也进行了比较。结果表明:用钼酸铵作着色剂,并采用先镀镍,后着色的工艺,通过控制着色处理的工艺参数,可获得不同的色彩,并可保持镀层原有的耐磨、耐蚀性能。最后对形成彩色镀层的机理也进行了初步分析。更多还原

【Abstract】 The preparation of colored electroless Ni-P coatings on the surface of steel was investigated.The influence of various technical factors on the color of the coatings was analyzed.The colored coating’s wear resistance and corrosion resistance were contrasted.Results show that when ammonium molybdate is used as coloring agent and color the coating after it was nickel plating,different kinds of colors can be obtained by controlling the processing parameters with the unaltered wear and corrosion resistance.Forming mechanism of the colored coatings was also discussed.更多还原
