摘要: 采用直流磁控共溅射法,通过一步法、两步法工艺在衬底为SiO2基体上制备了厚度为500 nm的Ni3Al薄膜,X射线衍射(XRD)和透射电镜(TEM)等测试表明,一步法工艺制备的Ni3Al薄膜为(111)取向的多晶型晶体结构金属间化合物优于两步法工艺。采用光学显微镜观察Ni-Al合金薄膜和金属间化合物Ni3Al薄膜经高温氧化后的形貌,结果表明,Ni3Al金属间化合物薄膜的高温抗氧化性能明显优于Ni-Al合金薄膜。

Abstract: By means of DC magnetron co-sputtering, a 500 nm thick Ni3Al thin film was prepared on the substrate of SiO2 by one-step method or two-step method. Test results of X-ray diffraction(XRD) and transmission electron microscopy(TEM) show that the (111) oriented intermetallic compound with polycrystalline structure in Ni3Al thin film prepared by one-step method is better than that by the two-step process. The morphology of Ni-Al alloy thin film and intermetallic compound Ni3Al thin film after high temperature oxidation was observed by means of metallographic microscope. The results show that the high temperature antioxidant properties of Ni3Al intermetallic compound films are obviously better than the Ni-Al alloy films.

Key words: Ni3Al thin film, magnetron sputtering, microstructure, high temperature oxidation resistance
