ZTA/A356复合材料的摩擦磨损性能研究

Study on abrasive properties of ZTA/A356 composites

摘要:

利用热压烧结制备了ZTA陶瓷预制体,然后通过压力浸渗工艺制备了 ZTA/A356复合材料,同时对复合材料的摩擦磨损性能进行了测试分析.试验结果表明,ZTA/A356复合材料的体积损失约为 A356基体铝合金的1/4,且复合材料的摩擦磨损性能随ZTA颗粒粒度的减小先下降再提高.

Abstract:

In the present study,ZTA ceramic perform were firstly prepared by hot press sintering,and then A356 was poured into the ZTA ceramic perform to fabricate ZTA/A356 composite by pressure infiltration process.The friction and wear properties of ZTA/A356 composite were addressed.The results show that the ZTA/A3 5 6 composite is about a quarter of the volume losses of A3 5 6,and the wear resistance properties of composite firstly decrease and then increase with the decrease of ZTA particle size.
