Is there a need for iron phosphate coating in a dry film lubrication application?

Hello,

Besides corrosion protection I was wondering, is there an advantage of iron phosphate coating steel parts in regards to dry film lubrication? If so, what are those advantages? Are there testing procedures that would support the claims? If so, what tests were ran and the findings?

Thank you,

It will stick much better if you use a phosphate. My personal opinion is that a fine zinc phosphate is far superior to iron phosphate, but a bit more expensive.
