Effect of Wettability on Tribological Properties of Porous UHMWPE

摘要：

　　Porous UHMWPE with different characteristics are prepared by hot press molding in Metallographic Sample Mounting.Friction and wear loss of porous UHMWPE samples are studied under different loads and lubricant on an improved tribological tester.The friction coefficient and wear loss of samples with porosity of 5.44% are lower than that of samples with porosity of 10.17%.Thickness of porous layer has little effect on the tribological properties of porous UHMWPE.Contact angle remarkable decreases with increasing porosity of UHMWPE samples.The change of wettability is the primary cause of the improving tribologicai properties of porous UHMWPE.
