Q. In phosphating, what coating thickness should be maintained for carbon steel components? Will the coating thickness differ from part to part after phosphating? —T.J.

A. By thickness of the coating, I assume you mean the powder applied after phosphating. The coating thickness is related to the particular powder used. Each powder will have a range of thickness on the Technical Data Sheet (TDS) supplied with the coating. Typical film thickness is around 2 to 3 mils. You may want a thinner coating for cost savings, or you may want a heavier coating for better edge coverage and performance. The coating thickness is not affected much by the phosphating.
