Phosphating comparison info


Hello all,

I am looking for some real basic information on the differences between various phosphating chemistries available - Zn phos, Ca modified Zn phos and Mn phos. Could the experts in this forum recommend good sources to learn the crystal structure differences, physical and chemical property differences and advantages/disadvantages comparison among these processes ? If I have a steel part that needs phosphating, how do I choose among these three options ?

Is there a video or a book source available on this topic?

Best regards and thanks to all help in advance!

Re books I suggest "Phosphating of Metals" [link is to info about the book at Amazon] By W Rausch or "Phosphating & Metal Pretreatment" [link is to info about the book at Amazon] by Brian Freeman.

Ca mod zinc phosphating is usually prepaint Zinc phosphating processes range from lightweight prepaint to heavyweight wire and tube draw processes. Manganese phosphate is used for its wear and corrosion resistance. With such a range of processes available it would be most unwise to self specify.
