| 摘 要： | 研究了高速电弧喷涂（HVAS）的几种Fe-Al复合涂层的耐高温腐蚀行为，用SEM观察分析了腐蚀表面的形貌和成分、涂层截面的组织结构.结果表明：随温度升高，4种Fe-Al涂层的腐蚀增重都增加，添加Cr3C2比添加WC或不添加任何增强的Fe-Al涂层有更高的耐腐蚀性. Fe-Al/Cr3C2涂层外表面形成了铝和铬的氧化物，阻止了氧化的进一步进行.

| Abstract: | The high temperature corrosion performance of High Velocity Arc Sprayed(HVAS) Fe-Al composite coatings on plain sted 20 G was studied by mass change measurements,while surface morphology of the corroded samples were analyzed by SEM.Results show that with the increasing of temperature,the corrosion rate of all Fe-Al coatings also increased,the corrosion resistance of the Fe-Al coating with addition of Cr3C2 is superior to those without or with addition of WC.An oxide scale consisted of Cr and Al oxides forme... |
| Keywords: | HVAS high temperature corrosion Fe-Al coating |
