背景技术Background technique
不锈钢表壳、表面为白色锡钴合金镀层要求具有光亮的外观，耐磨损，耐腐蚀。现有技术表面镀层包括预镀镍层、光亮铜层及白色锡钴合金镀层，该结构中由于镍层和铜层的膨胀系数不同，导致热形变不同，产生的热应力容易导致镀层的脱落。由此可见，上述现有不锈钢基体层镀层结构仍存在有诸多的缺陷，而亟待加以改进。The stainless steel case and the surface of the white tin-cobalt alloy coating require a bright appearance, wear resistance and corrosion resistance. The prior art surface coatings include pre-plating nickel layer, bright copper layer and white tin-cobalt alloy coating. In this structure, due to the different expansion coefficients of the nickel layer and the copper layer, the thermal deformation is different, and the thermal stress generated is easy to cause the coating layer to fall off. It can be seen that the above-mentioned existing stainless steel substrate layer coating structure still has many defects, and needs to be improved urgently.
