【摘要】：为了寻找一种环保、低温不锈钢着色新工艺,以钼酸铵为主着色盐,添加多种不同添加剂对不锈钢进行着色,通过正交试验优选着色工艺。通过控制着色时间,得到了金黄色、深红色、绿色、深绿色、黑色等多种色彩的着色膜。采用X射线能谱仪(EDAX)和扫描电子显微镜(SEM)等分析了着色膜的表面形貌和元素组成;通过电化学测试方法和机械摩擦法研究了着色膜的耐腐蚀性和耐磨性,并分析其机理。结果表明:着色膜致密、色泽光亮、鲜艳,主要成分为Mo O2,不锈钢着色后耐腐蚀性及耐磨性大幅提高;本工艺稳定、常温可操作,具有很好的应用前景。
[Abstract]:In order to find a new process for coloring stainless steel at low temperature and environmental protection, ammonium molybdate was used as the main coloring salt, various additives were added to coloring the stainless steel, and the coloring process was optimized by orthogonal test. By controlling the coloring time, the coloring films of gold, deep red, green, dark green, black and so on are obtained. The surface morphology and elemental composition of the colored film were analyzed by X-ray energy spectrometer (EDAX) and scanning electron microscope (SEM), the corrosion resistance and wear resistance of the colored film were studied by electrochemical measurement and mechanical friction, and its mechanism was analyzed. The results show that the coloring film is compact, bright and bright, and the main component is Mo O _ 2. The corrosion resistance and wear resistance of stainless steel are greatly improved after coloring, and the process is stable and operable at room temperature, which has a good prospect of application.
