摘要
Abstract
This study reported an investigation on the effects of gamma-ray irradiation modification above the melting point on the wear resistance of polytetrafluoroethylene(PTFE).The crystalline structure and tribological properties of PTFE before and after irradiation were characterized using differential scanning calorimetry,scanning electron microsco-py,X-ray diffraction,Fourier-transform infrared spectroscopy,and tribological testing.Results demonstrated that irradi-ation significantly enhanced PTFE's crystallinity.Under optimized conditions,the modified PTFE exhibits a 3.31-fold improvement in wear resistance and a 78%reduction in friction coefficient,demonstrating superior tribological perfor-mance.关键词
