Hard chromium in hard chromium process is a kind of chromium plating.
镀铬有两种的,一种是装饰铬工艺的装饰铬,一种是硬铬工艺。
硬铬是比较好的一种增加表面硬度的办法,但是它的优缺陷很多,所以好多状况下都没采用。
硬铬优点一,表面光亮度好,
硬铬优点二,不会生锈,一点锈斑都不会有;
硬铬优三,镀的进程中原零件变形小。
硬铬优四,假如零件尺寸不到位,可以通过加几丝铬来到达尺寸。
硬铬优点五,表面比较美观。等等
硬铬电镀的要素:
1.阴极:被镀物,指各种接插件端子。
2.阳极:若是可溶性阳极,则为欲镀金属。若是不可溶性阳极,大部分为贵金属(白金,氧化铱).
3.电镀药水:含有欲镀金属离子的电镀药水。
4.电镀槽:可接受,贮存电镀药水的槽体,一般思索强度,耐蚀,耐温等因素。
5.整流器:提供直流电源的设备。
