在硅酸盐体系中,利用微弧氧化双脉冲电源在Ti6Al4V合金表面制备了以Ti O2为主晶相的陶瓷膜层。通过XRD,SEM和EDS等技术分析了相组成,表面、截面形貌和元素含量变化的研究。讨论了不同反应时间对微弧氧化陶瓷膜组成、形貌和元素含量的影响。结果表明:在硅酸盐体系中,制备了以Ti O2为主晶相的陶瓷膜层。随反应时间的延长,膜层表面颗粒的数量有所减少,但颗粒和膜层表面的孔洞变大。膜层中Al、Ti和P元素含量逐渐变小,而V元素含量是先增大后减小。
In the silicate system, a ceramic film with Ti O2 as the main crystalline phase was prepared on the surface of Ti6Al4V alloy by using micro-arc oxidation double pulse power. The phase composition, surface morphology, cross section morphology and elemental content were analyzed by XRD, SEM and EDS techniques. The effects of different reaction time on the composition, morphology and elemental content of MAO coatings were discussed. The results show that ceramic coatings with Ti O2 as the main crystalline phase are prepared in the silicate system. With the extension of the reaction time, the number of particles on the surface of the film decreased, but the pores on the surface of the particles and the film became larger. The contents of Al, Ti and P in the film gradually decrease, but the content of V increases first and then decreases.
