摘 要: 研究了TA2鈦板復合氧化(熱氧化與陽極氧化的迭加)獲得氧化膜的形貌、成分和耐蝕性。結果表明，迭加方式不同，氧化膜形狀特征不同。經復合氧化處理后，氧化膜外層由TiO2和Ti2O3組成，內層由Ti2O3 和TiO組成；隨深度的增加，TiO2含量逐漸減少，TiO含量逐漸增加，Ti2O3含量先增加后減少。復合處理后，TA2耐蝕性顯著提高。

Abstract:The morphology, composition and corrosion of different complex oxidizing films on TA2 titanium were investigated, which were prepared by combining anodic oxidizing and thermal oxidizing.The results show that films with different features are expected if the different combination methods are adopted. All complex oxidizing methods can produce oxide films, whose outer layers are composed of TiO2 and Ti2O3, and the inter layers of Ti2O3 and TiO. With the depths from the surfaces increase, the content of TiO2 gradually reduces and TiO increases; however, the content of Ti2O3 firstly increases and then decreases. From complex oxidizing, the corrosion resistance is markedly improved.
Key words: TA2;complex oxidizing;corrosion resistance
