摘要
以磁控溅射法在316不锈钢上制备了TiN中间层厚度约为0.7μm,表面Au–Cu合金层厚度约为0.2μm的玫瑰金色复合薄膜,并对其进行耐人工汗液腐蚀和耐磨损性能测试。结果发现,TiN层具有良好的耐磨损性能,但腐蚀试验后复合膜层发生了明显变色。采用光学显微镜、扫描电镜、能谱分析和X射线光电子能谱仪分析了复合薄膜的变色机理。结果表明,该玫瑰金色薄膜表面变色主要与Cu元素的氧化有关。
A rose gold composite film comprising a 0.7μm-thick TiN intermediate layer and a 0.2μm-thick Au-Cu alloy top layer was prepared on 316 stainless steel by magnetron sputtering,and its resistance to corrosion in artificial sweat and abrasion was tested.The results showed that the TiN layer had good abrasion resistance,but the composite film discolored after corrosion test.The discoloration mechanism was studied by optical microscopy,scanning electron microscopy,energy-dispersive spectroscopy,and X-ray photoelectron spectroscopy.The results indicated that the discoloration of the rose gold composite film is mainly related to the oxidation of Cu element in its surface.
