| Abstract: |
| With the help of chemical agents, three kinds of mechanical zinc-coatings were achieved of 325 mesh, 800 mesh spherical zinc powders and the mixture of the two with equal quality. The surface topography and section morphology of the coatings were observed and the structure feature of coatings obtained by zinc powder with differen size was analyzed. The corrosion resistance were detected by neutral salt spray test . The result shows that the corrosion resistance of 325 mesh zinc-coating is worse than the others, while the 800 mesh zinc-coating is best . The corrosion resistance of the mixed-zinc coating is close to 800 mesh coating. |
