Introduction of Composite Plating

It refers to multi-coating layer. i.e. materials of 2 types shall be coated onto the copper tube in sequence. First layer of a nickel-cobalt alloy is to be coated onto the copper tube as intermediate layer, based on which the second layer of Chrome shall be done as anti-wearPlating Technics:

Composite plating is of Hard Chrome coating, there are two types of so called niclel-cobalt alloy, of which one is amido-sulfonic acid system with nickel aminosulfonate & cobalt aminosulfonate as raw materials whereas the other is sulfuric acid system with nickel sulphate & nickel cobalt as raw materials. The former is superior to the latter in technics for nickel sulphate with high stress likely to drop out from coating. By contrast, amido-sulfonic acid system with lower stress of good stability.

Advantages

Nickel-Cobalt coating as a transitional layer to increase the pass life of liquid metal, in other words, as the expansion factor of copper and chrome is totally different, in the process of heating and cooling, expansion shrinkage will give rise to the drop off from coating. Therefore, before chrome coating, a transitional layer of nickel-cobalt functions a buffer to free from the drop out problems, which drastically decrease the impact onto the coating in the process of heating and cooling increasing the pass life.

Temperature:20℃, (1E-6 /K or 1E-6 /℃)

Metal Expansion Factor
Copper 6.20
Nickel 13.0
Chrome 17.5
