Proper Coating Thickness
In phosphating, what coating thickness should be maintained for carbon steel components? Will the coating thickness differ from part to part after phosphating?
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.
