Iron phosphates are heavier coatings and mostly used for holding oil during running in.

Typical applications are gears,valve stems (on car engines for example).

Zinc phosphates are lighter (some can still be very heavy) and these go from oil holding (not so common heavy coat) to lighter coats used under paint to give the paint better adhesion (very good around damage for stopping the paint bubbling off).

As where to find more information & supply - pick a few supply houses of process from this web site - one is bound to help you
