Industrial or hard chrome plating is the electro-chemical process of depositing chrome directly on the base metal of the part. It is used primarily for wear resistance and it does give a limited amount of corrosion protection. The most common example of hard chrome plating would be hydraulic cylinders. Many other mechanical parts are also hard chrome plated for wear resistance.
Hard chrome can be deposited on steel, stainless steel, high nickel alloys, and copper alloys. Although it is possible to plate chrome directly on aluminum, only a few companies are capable of doing this. Quality Plating Co. is not capable of hard chrome directly on aluminum.
The coating thickness varies from 0.000050" to 0.050". As all electroplating the coating thickness will vary according to the geometry of the part being plated. Points, edges and the top & bottom of the part will build up more chrome than the recessed areas, insides of corners and center of parts. The uneven buildup becomes more prevalent as the coating thickness increases. For this reason many parts are ground after plating to bring the part to size.
