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.
phosphate coating reaction is simply known as the reaction between phosphoric acid and metal (acid – base reaction). metalic phosphate becomes insoluble on the surface and forms a layer with metalic colour.
