Phosphatizing, also called phosphating or phosphate conversion coating, is a metal pretreatment primarily used to prepare steel for paint or coatings and to prevent corrosion. Phosphatizing is termed a conversion coating because, unlike paint or traditional coatings, it does not lie on the surface of the metal, but rather the surface of the metal is chemically changed to a new substance. The coating will, therefore, not chip- or scratch-off exposing the base material to corrosion and wear.

Super Shot Peening can provide phosphate coatings for very large (up to 25 feet in length) and very small parts. We offer both zinc and manganese phosphate coatings. Both types produce components with gray or blue-gray, non-reflective, non-metallic, non-conductive, "velvety" finishes.

Although—as with all of our services—phosphating can be performed in the field, most of our phosphating jobs are performed on-site. Rush jobs are easily accommodated. In fact, many jobs have been completed within a period of only one or two hours while our client's driver has waited on-site. Please contact us for availability of our tanks.
