High-temperature Properties of AlSiCrTi Coating on Ti Alloy Surface Prepared by Slurry Roasting Process
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.
