等离子喷涂MCrAlY涂层的高温氧化性能
High Temperature Oxidation Properties of Plasma Sprayed MCrAlY Coatings
摘 要
采用大气等离子喷涂（APS）设备制备了两种含有不同氧化物（Cr2O3和Al2O3）陶瓷成分的MCrAlY （MCrAlY-CrO和MCrAlY-AlO）涂层，并使用光学显微镜、扫描电镜、X射线衍射仪及显微硬度计等仪器设备，分析了涂层的微观形貌、物相组成及硬度，并对两种涂层进行了高温氧化试验。结果表明：大气等离子喷涂得到的两种MCrAlY涂层中含有Cr2O3，Ni3Al，Al2O3和部分非晶相，其结构为平行于涂层与基体结合面的层状结构，涂层中含有半熔化颗粒、微裂纹及灰黑色氧化物；在高温氧化试验中，MCrAlY-CrO涂层与MCrAlY-AlO涂层均表现出较好的耐高温氧化性能，这是因为在高温状态下涂层表面分别生成了铬和铝的氧化产物，对涂层起到了保护作用。

Abstract
Two MCrAlY (MCrAlY-CrO and MCrAlY-AlO) coatings with different oxide (Cr2O3 and Al2O3) ceramic compositions were prepared by atmospheric plasma spraying (APS) equipment, and the microscopic morphology, phase compositions and hardness of the coatings were analyzed by optical microscope, scanning electron microscope, X-ray diffractometer and microhardness tester. The high temperature oxidation tests were carried out on the two coatings. The results show that the two MCrAlY coatings prepared by APS contained Cr2O3, Ni3Al, Al2O3 and some amorphous phases. The structure of the two coatings was a layered structure parallel to the bonding surface of the coating and the substrate. There were semi melted particles, micro cracks and grey oxides in the coatings. During the high temperature oxidation test, both MCrAlY-CrO coating and MCrAlY-AlO coating showed good high temperature oxidation resistance, because the oxidation products of chromium and aluminum which could protect the coatings, were formed on the surface of the coatings at high temperature.
