国营青山机械厂生产的某些薄壁零件,由于形状特殊,机械抛光难于保持同向,故抛光后其表面抛光的微小擦痕呈各向异性。众所周知,不同方向的痕迹在同一光源下,具有不同的折射与反射能力。因此,零件经过氧化(发兰)后,表面色泽不一,有发花现象,严重影响零件的外观质量,为解决此问题,原工 Some of the thin-walled parts produced by the state-owned Qingshan Machinery Factory are anisotropic because of the special shape and the difficulty that the mechanical polishing can keep in the same direction. As we all know, traces of different directions in the same light source, with different refraction and reflection. Therefore, the parts after oxidation (hair blue), the surface of different colors, there is the phenomenon of hair, the appearance of a serious impact on the quality of parts, in order to solve this problem, the original
