采用 B4C、 TiO2、Al 以及 Fe 基自熔合金粉末为前驱体，利用激光熔覆技术在钢基体上制备 TiB2+TiC颗粒增强Fe基复合涂层。结果表明，激光熔覆过程通过B4C?TiO2?Al反应生成了均匀分布于基体的TiB2?TiC复合陶瓷相。TiB2颗粒呈长条块状，TiC以不规则形状分布于基体中。涂层具有比基材1045钢更好的耐磨性能，但涂层的摩擦因数小。

Steel matrix composites reinforced with TiB2+TiC reinforcement were produced by laser melting mixture of B4C, TiO2, Al and Fe-based self-melting alloy powders. The results show that TiB2+TiC ceramic particles were synthesized from the reaction of B4C, TiO2 and Al alloys during laser cladding process. The reinforcement particles were evenly distributed in the coating. TiB2 grew in rectangle shape, but TiC presented irregular cubic shape. The wear resistance of the coating was higher than that of the substrate of 1045 steel;meanwhile, the friction coefficient of the coating was considerably lower than that of 1045 steel.
