What is phosphating

Mostly used petreatment method is known as "phosphating". Phosphate coating is the layer form on surface which includes iron, zinc or manganese crystals.

There are three types of phosphate coating; iron phosphate, zinc phosphate and manganese phosphate. Generally it is used for coating iron and steel surfaces. Immersion and spraying are the most common application methods.
