Yttrium silicate coatings for SiC coated C/C composites prepared by atmospheric plasma spraying

采用等离子喷涂(Atmospheric plasma spraying , APS)法在炭/炭复合材料碳化硅(SiC)内涂层表面制备了硅酸钇涂层.分别采用XRD和SEM分析了所得涂层的微观结构,并测试了带有SiC/硅酸钇复合涂层的炭/炭复合材料试样在1500℃静态空气中的抗氧化性能.结果表明:通过调节喷涂粉料中的SiO2和Y2O3的摩尔比,可制得Y2SiO5、Y2Si2O7、Y2Si2O7/Y2SiO5和Y4Si3O12/Y2Si2O7/ Y2SiO5四种不同结构的硅酸钇涂层;1500℃氧化73h后,SiC/Y4Si3O12/Y2Si2O7/Y2SiO5涂层试样的氧化失重速率相对较低,仅为1.01×10-4 g · cm-2 · h-1.
