摘要/Abstract

摘要： 选用石化设备常用材料20g为基体,使用电弧热喷涂技术在基体表面喷涂稀土铝合金层,并进行重熔
处理。通过拉伸试验,在pH=9的Na2CO3 溶液和pH=6的H2SO4 溶液中的腐蚀试验研究涂层性能的变化。结
果表明,重熔处理后稀土铝层与基体的结合强度提高了近73%,抗腐蚀性能也有显著提高。并分析了涂层结合强度
和抗腐蚀性能提高的原因。

关键词: 热喷涂 , 重熔处理 , 金属腐蚀 , 结合强度

Abstract: 20g matrix which is common used in refinery equipment and sprayed rare-earth aluminum alloy on it and remelted it was selected. The performance of the coating was studied through tension test and corrosion tests of pH=9 Na2CO3 and pH=6 H2SO4 solution. The result shows that the bond strength of rare-earth aluminum alloy and the matrix increases at about 73% and corrosion resistance has also significantly improved after remelting treatment. Finally, the reasons of the improvement of bond strength and corrosion resistance were analyzed.
