采用反应喷涂技术在钢表面制备了三元硼化物金属陶瓷涂层,为了进一步提高涂层的结合强度,对所制涂层进行了感应加热处理,研究了感应加热工艺对涂层组织和界面结构的影响规律,并测试了相应涂层的显微硬度和耐磨性.结果表明:涂层经过980 ℃感应加热温度后,金属陶瓷层组织无变化,由Mo_2FeB_2硬质相和α-Fe基体相组成,涂层的显微硬度达到HV_0.1 1 200,具有较高的耐磨性.
Mo_2FeB_2 ternary boride cermet coating was prepared on the steel substrate by reactive flame spraying. The induction heating was chosen for the purpose of improving the bonding strength of the coating. The effect of induction heating on the microstructure of the coating and its interracial microstructure were studied. Micro-hardness of the coating was tested as well as its wear resistance after heating treatment. The results show that after such treatment the coating is unchanged and composed of matrix phase α-Fe and horniness phase Mo_2FeB_2 with high micro-hardness(HV_0.1 1 200) and wear resistance when the induction heating temperature reaches 980 ℃.
