| 摘 要： | 使用T11及THT07-135高温磨损实验机对高速电弧喷涂(HVAS)Fe-Al/Cr3C2复合涂层进行了滑动摩擦特性的研究,用SEM观察分析了磨斑的形貌和成分、涂层截面的组织结构。结果表明:摩擦副对Fe-Al/Cr3C2复合涂层的摩擦磨损性能影响不大;载荷增加,涂层表面的磨痕增宽,摩擦因数与磨损率减小,磨痕处的氧化物和烧结物增多;温度对涂层的摩擦磨损性能影响不大,高温下的“跑合”期比常温下的短;涂层的磨损机理主要是剥层磨损,在高温高载荷的磨损条件下,磨痕处出现氧化物和烧结物,在剥层磨损的同时还存在部分粘着磨损。 |

| Abstract: | T11 and high temperature machinery THT07-135 were used to analyze tribological properties of high velocity arc sprayed(HVAS)Fe-Al/Cr3C2 composite coating,wear scar images and composite microstructure were analyzed by SEM.Results show that courter part does little effect on wear properties of coating;With the increase of loads,wear scar becomes wide,wear coe-fficient and abrasion become low,oxidation and sinters increase.Temperature does little effect on wear resistance of coating."Run-up" periods of coating at high temperature are shorter than at room temperature.The main wear mechanism of coating is shell tribology.At high temperature loads,wear areas have more oxidation and sinters,and there also have some viscous wear. |
| Keywords: | HVAS tribology Fe-Al/Cr3C2 coating mechanical wear wear and lubricate |
