Study on the wear-resistance Cu/Ti_3AlC_2 composite

With Ti,Al,C,Cu as raw material,composite Ti3AlC2 is made by means of mechanical alloying and spark plasma sintering(SPS).We analyze its structural performances in detail: the micro-hardness of the Cu/Ti3AlC2 composite,prepared with SPS method,will increase with the up of Ti3AlC2 content;at the same conditions of 900 ℃ and 20 min heat preservation,its hardness with 15vol%Ti3AlC2 is 2 times of that with pure Cu;its wear-resistance of the composite with 5vol%Ti3AlC2 would be decreased over 30%.It comes to a conclusion that suitable content of Ti3AlC2 may increase the wear-resistance of the composite.
