摘　　要：研究了稀土氧化物Y_2O_3对Ti-6Al-4V合金表面原位自生Ti C-Ti B_2颗粒增强涂层结合力的影响。结果表明,在Al-B4C体系涂层中添加少量稀土氧化物Y_2O_3不仅可大幅提高内/外层界面结合强度,而且改变了涂层的破环方式。The effect of Y2 O3 on the adhesion of in situ Ti C-Ti B2 particulate reinforced coating prepared on the surface of Ti-6 Al-4 V alloy was investigated. The results show that the addition of Y2 O3 in the Al-B4 C system can not only increase the adhesion of interface between outer layer and inner layer, but also change the way of the coating broken.
