摘　　要：以铜粉、TiCN粉以及由化学镀法制备的铜包覆钨复合粉末为原料,采用放电等离子烧结技术制备TiCN/W-Cu复合材料,研究了复合材料的组织、硬度和高温摩擦磨损性能。结果表明:复合材料组织致密,细小的TiCN颗粒弥散分布在钨和铜相界处;复合材料的相对密度为97.9%,硬度为282.7 HV,分别比W-Cu合金提高了0.6%和22.2%,常温与高温下的磨损率均低于W-Cu合金,25℃下复合材料的磨损机理以磨粒磨损为主,随着温度的升高,转变为疲劳磨损、黏着磨损与氧化磨损。Taking copper power,TiCN power and copper-coated tungsten composite powder by chemical plating as raw materials,TiCN/W-Cu composites was prepared by spark plasma sintering technology.The microstructure,hardness and high temperature friction and wear properties of the composite were studied.The results show that the microstructure of the composites was compact,and the fine TiCN particles were dispersed at boundaries between tungsten and copper phase.The relative density and hardness of the composites were 97.9%and 282.7 HV,which were 0.6%and 22.2%higher than those of W-Cu alloy,respectively.The wear rate of the composite was lower than that of W-Cu alloy at room temperature and high temperature;the wear mechanism of composites at 25℃was abrasive wear and changed to fatigue wear,adhesive wear and oxidation wear with increasing temperature.
