摘要

采用TI-C-AL-NI系SHS熔铸制备TIC颗粒增强钢基表面复合材料

研究了其组织和耐磨性。结果表明:用SHS熔铸法制备的钢基表面复合材料强化相和基体结合良好;表层TIC颗粒分布密集

颗粒均匀圆整

粒度为1

ΜM;表面硬度HV高达950

且硬度由表层向基体呈梯度分布;磨损时密集的高硬度的细小圆球状TIC颗粒大大降低了磨损率;耐磨性比基体提高5.6倍。

Abstract

The microstructure and wear resistance of TiC reinforced steel matrix surface composites prepared in Ti-C-Al-Ni system by SHS-casting method were investigated.The results show that the reinforced particle well bonded with the steel matrix in the steel matrix surface composites in the SHS-casting method.Uniform and round TiC particle with size 1～2 μm is distributed in the matrix

and the surface hardness with gradient distribution from the surface to the steel matrix is more than 950 Hv.The wear resistance of the composites is 5.6 times higher than that of the steel matrix

resulting in the dense fine round TiC particle with high hardness significantly decreasing the wear rate during wear process

showing excellent wear resistance.
