摘要：

Irradiation crosslinking is one of the most important methods to modify UHMWPE. It can effectively improve the hardness, creep resistance and abrasion resistance of this material. In order to eliminate free radical, increase material strength, abrasion resistance and fatigue resistance of creep, this study uses Co60-gamma to modify UHMWPE in vacuum, with the irradiation dose of 30, 60, 90, 120 Kgy respectively. Its mechanical properties, microstructure, degree of crosslinking and crystallinity are analyzed, the results show that the modified UHMWPE's impact strength decreased, elongation basically remain unchanged, tensile fracture strength and tensile yield strength increased.
