Phosphating is a conversion coating for treating the surface of iron and steel components, where metal-phosphate layers are formed on the base material.

It is mostly used as a pre-treatment before we apply another means of protection, usually coating or painting. As well as protecting against corrosion, it reduces friction between sliding components – we’re all about protection and performance.

In its basic form, phosphating involves immersing a component in a solution, which converts the surface of the metal into a layer of microscopic phosphate crystals.

It’s commonly applied to steel, iron and other ferrous metals.
