摘要: 采用等离子喷涂技术制备了NiCr/Cr2C3涂层，并采用SEM、XRD、马弗炉和高温热膨胀仪对涂层的结构、物相和热震性能进行了表征。结果表明：等离子喷涂NiCr/Cr2C3涂层呈层状结构，涂层的主晶相为NiCr和Cr2C3相，涂层在700℃、800℃和850℃时抗热震性能良好，均满足使用要求。
Abstract: The NiCr/Cr2C3 coating was prepared by atmospheric plasma-spray technology. The microstructure, phase composition and thermal shock resistance property were studied by SEM, XRD and muffle furnace. The results show that the NiCr/Cr2C3 composite coating consisted of elongated lamellae. The main phase compositions of coating were NiCr and Cr2C3. The coating exhibited excellent thermal shock resistance property and fulfilled the requirement at 700˚C, 800˚C and 850˚C.
