摘    要:改善超高分子量聚乙烯(UHMWPE)臼杯的耐磨性能是提高人工髋关节使用寿命的关键.本文在UHMWPE基体上采用非平衡直流磁控溅射沉积类石墨碳(GLC)薄膜,用扫描电镜、台阶轮廓仪考察了薄膜形貌和表面粗糙度,拉曼光谱分析了GLC薄膜的结构.用划痕仪和球-盘式摩擦磨损机研究了GLC薄膜与UHMWPE基体的界面结合力和GLC薄膜的摩擦磨损性能.结果表明:磁控溅射法制备的GLC薄膜与基体结合力大于90 N,且对表面粗糙度没有影响;表面镀覆GLC薄膜的体积磨损率为1.6×10-17 m3/(N·m),是UHMWPE的1/19.

关 键 词:GLC薄膜  超高分子量聚乙烯  界面结合力  摩擦磨损

Abstract:Great interest has been attracted on the improvement the wear resistance of ultra high molecular weight polyethylene(UHMWPE) as acetabular cup of artificial hip joints.Graphite-like carbon(GLC) film was deposited on UHMWPE substrate by unbalanced DC magnetron sputtering process.The morphology and surface roughness were characterized by SEM and surface profiler,and the microstructure was evaluated by Raman spectroscopy.The adhesion to substrate and friction and wear properties of the GLC film on UHMWPE subst...
Keywords:GLC film  UHMWPE  adhesion strength  friction and wear
