| 摘 要： | 通过铜加速醋酸盐雾腐蚀试验,研究了自封闭特性在Zn-Al-Mg-RE高速电弧喷涂层与舰船涂料结合成防腐复合涂层中的作用.经过480h的试验,在基体上直接涂装涂料的试样表面的划痕里充满了铁锈,而中间喷有高速电弧喷涂层的试样表面划痕里只有少量的白锈.这说明在腐蚀环境中,Zn-Al-Mg-RE高速电弧喷涂层表面的微观孔隙能够被自身的腐蚀产物堵塞,生成的腐蚀产物非常致密,能够阻止缺陷处继续被腐蚀.从试验结果可知在复合涂层体系中,高速电弧喷涂层的自封闭特性起到了积极的作用. |

| Abstract: | The action of the self-sealing behavior in anti-corrosion multilayer coating composed of Zn-Al-Mg-RE high velocity arc spray(HVAS) coating and shipping paint was investigated by chloride copper acetic acid spray test(CASS).The results show that the nicks on the surface of the sample without the metallic coating are filled by ferric oxide,whereas a little white rust can be seen in nicks of the anti-corrosion multilayer coating.In corrosive environment,the micro-pores on the surface of the Zn-Al-Mg-RE high velocity arc spray coating are blocked by itself corrosion products which are so compact that the defects can be prevent from corroding sequentially.In addition,the self-sealing behavior of the high velocity arc spray coating is beneficial to the multilayer coating. |
| Keywords: | Zn-Al- Mg-RE high velocity arc spray coating self-sealing corrosion |
