Reinforced zinc-silicate coating by adding sericite has been investigated. Contrasting wear resistance, corrosion resistance and water resistance performance of the modification coating and zinc-silicate coating by polarization curve, attrition experiment, immersion and water washout experiment. The research result shows that the sericite's corrosion resistance, and the synergistic effect of porous coating filled by the sericite and the corrosion products reduced the corrosion rate of corrosion. The sericite play a positive role. It enhanced wear resistance by reducing the friction coefficient, reducing coating plastic deformation, internal cracks in the coating to prevent the generation and expansion. The paint film interior may form one kind of compact level network structure, increases the coating the compactness, the enhancement paint film impermeability and the paint film intensity, enhances the water resistance. Primer coating is not limited to, expanding the application of coating space.
