What is the difference between hard chrome plating and decorative chrome plating? Xinsida will tell you
2015-04-21 1060
1. Relationship between chromic anhydride concentration and hardness在其它技术条件一样的时分，铬酐浓度低时硬度高。但浓度低，镀液变化快，不安稳。2.硫酸含量和硬度的联系在正常的镀铬技术标准中。铬酐与硫酸的比值应当保持在100：1。在其它浓度不变时，进步硫酸含量，铬层的 硬度也相应增高。但在二者比值为100：1.4，再进步硫酸含量硬
