Coating Morphology

Zinc phosphate coating is commonly used for corrosion protection of metallic materials, mainly mild steel. In this study, influence of the pH of phosphating bath on the surface morphology and corrosion resistance of zinc phosphate coatings on mild steel was investigated. The phosphate layers were deposited on steel from phosphating bath at different pH values (1.75 ~ 2.75). The surface morphology and composition of phosphate coatings were investigated via scanning electron microscopy (SEM), and energy-dispersive X-ray (EDX). The corrosion resistance of the coating was evaluated by polarization curves (anodic and cathodic) in an aerated 3.5% NaCl solution. The results showed that better surface coverage and corrosion resistance for the steel phosphated at pH 2.75.

Abstract Phosphating is most common method for surface treatment and finishing of ferrous and nonferrous metal. It has excellent corrosion resistance, wear resistance, adhesion and lubricating properties besides its economic values and speed of application. Steel is one of the cheapest materials used in various industries and it requires corrosion resistance therapy. This study aims to provide possible solution to the rusty issue on carbon steel product by improving coating stability using Defining–Measuring–Analysing–Improving–Controlling (DMAIC) method. The result proposed that zinc phosphate coating material has to replace current iron phosphate coating due to the former is more corrosion time resistant than that of the latter.
