Study on the Tribological Properties of Porous UHMWPE
Porous UHMWPE were prepared by hot press molding in Metallographic Sample Mounting. The tribological properties of normal UHMWPE and porous UHMWPE were studied under different loads and lubricant on an improved tribological tester. The friction coefficient and wear loss of porous UHMWPE are steady and low under low loads, which attribute to the porous structure and extrusion effect of lubricant in testing. The results also show that the lubricant of BSA is better than that of water by its high viscosity. Among the increasing of loads, friction coefficient and wear loss are enhance rapidly. Serious cutting is the wear mechanism for porous UHMWPE under high loads.
