分别采用GCr15和SiC球作为摩擦配副,研究了TC4合金的摩擦磨损性能及磨损表面的组织变化。结果表明:在相同摩擦载荷和磨损时间内,使用GCr15球作为摩擦配副时,TC4合金的摩擦系数较使用SiC为摩擦配副时的高,但磨损质量损失较小。TC4合金基体在两种摩擦配副下的磨损机制均主要为犁削磨损、粘着磨损和氧化磨损;使用GCr15球作为摩擦配副时粘着磨损和氧化磨损更加显著。
The friction and wear properties of TC4 alloy and the microstructure changes of the worn surface were studied by using GCr15 and SiC balls respectively. The results show that the friction coefficient of TC4 alloy is higher when using GCr15 ball as the friction partner than the friction pair of SiC with the same friction load and wear time, but the wear mass loss is small. The wear mechanism of TC4 alloy matrix under the two kinds of friction matching is mainly plow wear, adhesive wear and oxidation wear; Adhesion and oxidation wear is more significant when the GCr15 ball is used as the friction partner.
