What is Maximum Hard chrome plating Thickness

Apr 12, 2013· 2006. A. Theoretically yes, but hard chrome is too brittle (less than 1%) compared to 15% or more for steel and may spall or chip. For that thickness it will also be cracked. The cracks may be thin and shallow but, depending on process parameters, they may penetrate into the base material allowing for corrosion products to undermine it.

Pollution Prevention in the Plating Process

The traditional chrome plating process is the 100:1 bath, which means that the ratio of chromic acid (CrO3) to sulfate (SO4) should be 100:1 by weight, that is, 250g/l CrO3 to 2.5 g/l SO4. Excess sulfate in these solutions can affect plating quality and should be removed by the addition of barium carbonate.
