金属材料氧化和着色工艺设计

Process design of oxydizing and colouring of metals

金属材料表面经氧化和着色后，可提高其表面硬度、耐蚀性、耐磨性、耐光性和增加表面色彩。文中介绍了氧化、着色的工艺原理、生产流程、主要参数、设备选择、三废治理和环保措施等。

Thesurface hardness,corrosion resistance,abrasion resistance and light fastness as well as the surface colour of metals can be improved through oxidizing and Colouring processing.The technological principles,process flowsheet,main parameters,equipment selection,wastes disposal and environment protection are described in this paper.
