精密铸件的表面怎么处理

发布时间:2018-04-03点击量:76

精密铸件的表面处理是在基体材料表面上人工形成一层与基体的机械、物理和化学性能不同的表层的工艺方法。表面处理的目的是满足产品的耐蚀性、耐磨性、装饰或其他特种功能要求。 对于金属铸件,我们比较常用的表面处理方法是,机械打磨,化学处理,表面热处理,喷涂表面,表面处理就是对工件表面进行清洁、清扫、去毛刺、去油污、去氧化皮等

The surface treatment of precision castings is a method of artificially forming a surface layer on the surface of the base material that has different mechanical, physical and chemical properties from the base. The purpose of the surface treatment is to meet the corrosion resistance, wear resistance, decoration or other special functional requirements of the product. For metal castings, we commonly use surface treatment methods such as mechanical grinding, chemical treatment, surface heat treatment, and spray coating. Surface treatment is to clean, sweep, deburr, degrease, descale, etc. the surface of the workpiece.
