研究了金属钽在LiNO_3—助熔盐的熔盐体系中阳极氧化、生成表面硬质膜的工艺,并在应用稀土添加剂改善膜层,从而强化钽材,提高耐蚀性能。
The process of anodic oxidation of the metal tantalum in the molten salt system of LiNO_3-fluxing salt to produce a hard surfaced film was studied. The rare earth additive was used to improve the film layer to strengthen the tantalum material and improve the corrosion resistance.
