| 中文摘要: |
| 分别采用 325 目、800 目和 325 目+800 目等质量混合的球形锌粉,在活化剂的作用下进行机械镀锌,得到三种机械镀锌层。 观察了三种镀锌层的表面形貌和断面结构,分析了不同粒径锌粉所得镀层的结构特点,通过中性盐雾试验测试了镀层的耐腐蚀性能。 结果表明:325 目锌粉镀层的耐腐蚀性能最差,800 目锌粉镀层的耐腐蚀性能最好,325 目与 800 目等质量混合的锌粉镀层耐腐蚀性能介于两者之间,接近 800 目锌粉镀层。 |
| 英文摘要: |
| 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. |
