陶瓷粒子增强铝基复合材料制取新工艺及其磨损性能

New Technique of Making Aluminium Matrix Composite Reinforced by Ceramic Particles and its Wear Resistant Properties

提出一种制取陶瓷粒子增强铝基复合材料的新方法──渗透法。可在大气气氛下，于８５０～９５０℃温度范围内，不用外加压力或抽真空，通过助渗剂作用，使铝合金液体自动地渗入陶瓷粒子内部，从而形成结合良好的复合材料。并对其磨损性能进行了测试。

A new infiltration method of making aluminium matrix composite reinforced by ceramic particles is described. At the temperature of 850-950℃,without the additional pressure or vacuum,the melted aluminium alloy spontaneously infiltrated into ceramic particles to form composite by using infiltration aid in air.The wear resistance was also tested.
