Understanding of the advantages of hard chromium process and the basic elements of hard chromium electroplating
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。
