| 摘 要： | 分别采用射频溅射和射频反应溅射方式在AZ31镁合金表面制备了氧化铌涂层，并利用扫描电子显微镜、X射线衍射仪、X射线光电子能谱仪、多功能材料表面性能试验仪和电化学工作站对比研究了两种涂层的微观形貌、物相组成、附着力和耐腐蚀性能。研究结果表明，两种涂层都呈非晶柱状结构，铌的价态为Nb5+，对AZ31镁合金的腐蚀保护率达93%以上；与射频溅射沉积的氧化铌涂层相比，射频反应溅射沉积的氧化铌涂层的表面致密性和耐蚀性能更强，附着力提高约7.4倍。

| Abstract: | Niobium oxide coating was prepared on AZ31 magnesium alloy by RF sputtering and RF reactive sputtering. The microstructure, phase composition, chemical valence state, adhesion, and corrosion resistance of the coatings were studied by scanning electron microscope, X-ray diffractometer, X-ray photoelectron spectrometer, multifunctional material surface performance tester, and electrochemical workstation. The results show that both layers have an amorphous columnar structure, the niobium valence state of Nb5+, and excellent corrosion protection for AZ31 magnesium alloy up to 93% and above. Compared with RF sputtered niobium oxide coating, RF reactive sputtered niobium oxide coating has enhanced surface compactness, boosted corrosion resistance, and increased adhesion by about 7.4 times. |
