摘要
采用等离子喷涂方法制备了ＴｉＯ２ 纳米涂层，研究了其离子注入和抽出特性． 结果表明：等离子喷涂的氧化钛涂层具有多孔性纳米结构，纳米颗粒的尺寸为１０ ～１５０ ｎｍ ，主要由锐钛矿和金红石两种物相构成． 在电位扫描范围为１．０～１．５ Ｖ，电位扫描速率为２０，５０ 和１００ ｍＶ／ｓ 时，涂层表现出良好的Ｌｉ＋ 离子注入和抽出特性． 循环伏安试验表明氧化钛纳米涂层具有良好的电化学稳定性．
Plasma sprayed TiO 2 coatings possess porous nano_phase structure. The grains in the coatings have a particle size ranging from 10 to 150 nm. Moreover, all the three titania coatings investigated, especially one of the coating (Ⅱ), exhibits notable ion implantation properties, such as higher implantation current and electrochemical stability, which is due to their suitable porosity, higher specific area, fine grain and notable grain boundaries. The microstructure and electrochemical properties of plasma sprayed titania coatings can be controlled by plasma parameters.
