Q. Can you give me an economic analysis of the advantages of phosphate coatings of steel? L.A.Z.
A. The direct answer to this question is “No, I can’t.” However, I can give you a reference to a good book that discusses these coatings in great technical detail:The Phosphating of Metals
by Werner Rausch, ASM International, available on amazon.com
. I also did some Googling on the subject and found a number of references that may be useful to you.
