| 摘 要： | 采用微弧氧化在钛合金表面制备BaTiO3膜。讨论电解液组分、反应时间及电压对BaTiO3膜形态和相组成的影响,并评价BaTiO3膜的结合强度。结果表明,BaTiO3的生成量随电解液浓度和氧化时间的增大而增加;其表面形貌也受电解液浓度、电压和氧化时间的影响;电压降低,膜层的结合强度有增大的趋势。电压为80 V时,结合强度可达36.4 MPa,优于一般等离子喷涂技术获得的膜层结合强度。

| Abstract: | The barium titanate films have been grown on the surface of the titanium alloy by the micro-arc oxidation.The effect of the electrolyte composition,oxidation time,and micro-arc voltage on the structure and morphology of the films were discussed,and the adhesive strength of the BaTiO3 films was evaluated.The results showed that with increasing the concentration of electrolyte composition and oxidation time the more barium titanate films were formed.The morphology of the BaTiO3 films was influenced by the con... |
