采用熔烧法在TC11基体上制备铝化物涂层,对涂层的制备工艺进行了研究,利用扫描电镜(EDS)、X衍射仪(XRD)对涂层的形貌及相结构进行分析,并通过氧乙炔熔烧法对涂层的抗氧化性能进行测试。结果表明:在TC11表面可制备出膜基结合好的涂层,涂层以Al3Ti为主要相,厚度为70～100μm,该涂层可在高温下生成Al2O3,具有良好的瞬时抗高温氧化性。
The aluminide coating was prepared on the TC11 substrate by the sintering method. The preparation process of the coating was studied. The morphology and phase structure of the coating were analyzed by scanning electron microscopy (EDS) and X-ray diffraction (XRD) The oxidation resistance of the coating was tested by oxyacetylene melting method. The results show that the coating on the surface of TC11 can be prepared into a film-based coating with Al3Ti as the main phase and a thickness of 70-100 μm. The coating can form Al2O3 at high temperature and has good instantaneous high temperature oxidation resistance.
