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 35 feet in length on a double dip) and very small parts. We offer both zinc and manganese phosphate coatings. Both types produce components with black or blue-black, 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.
