金属的表面处理,仅仅抛得很光并洗得很干净,还不足以称为是理想的前处理,只有经过适当的化学浸蚀或喷丸冲击,使材料表面在一定光洁度的保证下,微观上呈现略微粗糙,才有利于进一步表面加工或镀复金属层。这是因为金属基体上的结晶组织的暴露能保证基体金属与镀层金属的晶体之间的紧密结合。作为金属物件的前处理工艺,喷丸法仍是目前有效可用的一种机械处理方法。统计表明,某些金属或非金届零件的喷丸处理不
Metal surface treatment, just throw very light and wash very clean, not enough to be called the ideal pretreatment, only through the appropriate chemical etching or shot peening, the surface of the material in a certain degree of finish under the guarantee, microscopic Showing a little rough, it is conducive to further surface processing or plating complex metal layer. This is because the exposure of the crystalline structure on the metal substrate ensures the close bond between the base metal and the crystal of the coated metal. As a pre-treatment of metal objects, shot peening method is still available and effective as a mechanical treatment. Statistics show that the shot peening of some metal or non-gold parts is not
