摘　　要：采用无机盐料浆熔烧法在Ti6Al4V钛合金表面制备了AlSiCrTi涂层,利用氧乙炔火焰在大气环境下熔烧涂层,经2000℃×10 min熔烧后,利用扫描电子显微镜(SEM)对比分析了AlSiCrTi涂层经熔烧氧化前后的表面和断面形貌,利用能谱仪(EDS)分析了熔烧氧化前后的表面成分变化,利用X射线衍射(XRD)分析了熔烧氧化前后的相结构。结果表明,AlSiCrTi涂层表现出很好的高温抗氧化性能,显著改善了Ti6Al4V钛合金在超高温环境下的使用性能。The AlSiCrTi coating were prepared on Ti6Al4V titanium alloy surface by slurry roasting process,and the coating was roasted by oxyacetylene blaze at 2000 ℃×10 min in air.The surface morphology,cross section,composition of the coating before and after the oxidization testing were analyzed by SEM,EDS and XRD.The results show that the high-temperature oxidation resistance of Ti6Al4V considerably improves by AlSiCrTi coating.
