过去的彩色不锈钢是在不锈钢表面形成一层透明的氧化膜,并通过这种透明表面氧化膜/金属界面对光线的干涉现象显示出各种色彩,但这种彩色不锈钢表面氧化膜存在耐磨性差、易划伤、弄污或褪色、变色的缺点。为了消除这些缺点,日本精工电子工业公司新近开发成功一种不锈钢着色新工艺。该工艺要点为,首先将不锈钢制品加以金属镀覆,随后热处理,使其表面金属镀层扩散渗入不锈钢表层一定深度, In the past, colored stainless steel formed a layer of transparent oxide film on the surface of stainless steel and showed various colors through the interference of light on the transparent surface oxide film / metal interface. However, this colored stainless steel surface oxide film has poor abrasion resistance Easy to scratch, stain or fade, the shortcomings of discoloration. In order to eliminate these shortcomings, the Japanese Seiko Instruments Inc. recently developed a new stainless steel coloring process. The process points for the first stainless steel products to be metal plating, followed by heat treatment, the surface of the metal coating diffusion into the surface of stainless steel to a certain depth,
