The advantages of high-efficiency hard chromium plating process:
1.Process does not contain fluorine, environmentally friendly products;
2.Excellent throwing ability;
3.The finely structured chromium plating layer, the number of micro-cracks is about600-1200Article/cm；
4.Using a new type of catalyst, the current efficiency is as high as26-30%, Does not corrode the anode;
5.No corrosion to steel and alloy steel;
6.Good ductility, the workpiece is not easy to burn;
7.The process is stable and contains only two components. The operation is simple and convenient ;
8.Pay attention to the analysis and control of chromic acid, trivalent chromium and sulfate content in daily production;
9. To control the deposition rate of the coating,Other hard chromium plating processes can be easily converted to this process.
