Oxidation-resistant rose gold plating and preparation process thereof

The invention discloses rose gold plating and a preparation process thereof. The rose gold plating comprises a metal matrix, the metal matrix is made of stainless steel, and the surface of the metal matrix is a rose gold plating body, wherein the rose gold plating body comprises 12-20wt% of Cu, 5-15wt% of Pd, 0.5-0.7wt% of Er, 0.1-0.2wt% of Nd and the balance Au. According to the rose gold plating, the Pd, the Er and the Nd are added, so that the rose gold plating has good oxidation resistance, and the color of rose gold cannot be changed after the rose gold is used for a long time; and the preparation process is simple and rapid, the hurt to operators and the damage to the environment caused by a conventional electroplating process are reduced, and great convenience is brought to electroplating operation. 本发明公开了种玫瑰金镀层及其制备工艺，包括金属基体，该金属基体材料为不锈钢，金属基体的表面为玫瑰金镀层，所述玫瑰金镀层的成分为：Cu12～20wt％、Pd5～15wt％、Er0.5～0.7wt％、Nd0.1～0.2wt％，剩余为Au；该玫瑰金镀层中添加有Pd、Er及Nd，因此具有良好的耐氧化性，长时间使用其玫瑰金颜色不会改变，并且制备工艺简单快捷，减少了常规电镀工艺给操作工人以及环境所带来的危害，给电镀作业带
