Method of applying zinc-phosphate conversion crystal coating

Abstract

A modified zinc-phosphate conversion coating method, presented as the Absorbed Solution Layer Phosphating (ASLP) coating method. This modified zinc-phosphate conversion crystal coating (ZPCCC) method is carried out in a reactor, containing metal substrate, a quantity of phosphate solution and a quantity of inert, solid filler particles, the quantity of phosphate solution being dependent on the solid filler particle's solution absorption ability. The ASLP process is carried out in an interface layer between the substrate and the solid filler particles, with the reactor being constructed to provide movement of treated parts and filler particles relative to each other, continually exposing surfaces of the substrate to fresh phosphate solution.
