摘要
采用放电等离子烧结法制各了Cu/Ti_3SiC_2复合材料,测试了不同Ti_3SiC_2含量、球磨速度以及混粉时间条件下制备的复合材料的相对密度、硬度以及抗弯强度,并观察了表面形貌以及显微组织,分析了高能球磨工艺对该复合材料组织和性能的影响。结果表明:在Ti_3SiC_2质量分数为20%、球磨速度为500r/min、球磨时间为6h时,可得到性能优异的复合材料;其相对密度为98.24%、维氏硬度为253.28HV、抗弯强度为1 450.98MPa。
Cu/Ti3SiC2 composites were prepared by spark plasma sintering （SPS）. Through the measurement of relative density, hardness and bending strength on the condition of different Ti3SiC2 contents, different milling speed and different mixing time, the effect of high-energy ball milling process on the properties of Cu/Ti3 SiC2 composites was concluded. Moreover, the microstructure of samples was observed. The result shows that when the Ti3SiC2 content is 20% , the milling speed is 500r/min and the mixing time is 6h, the Cu/Ti3SiC2 composite with excellent properties is available and its. relative density is 98.24% , Vickers hardness is 253.28HV and the bending strength is 1 450. 98MPa,
