摘要(Abstract)：

为改善Ti6Al4V的生物摩擦学性能,分别采用直径为4、6和10 mm的喷丸对其进行表面强化处理,然后用TR240粗糙度仪测表面改性层的表面粗糙度Ra,在MRTR多功能摩擦磨损试验机上以ZrO_2球/Ti6Al4V表面改性层为摩擦副进行人工唾液和透明质酸钠溶液润滑下的生物摩擦学试验,使用S-3000N扫描电子显微镜观察Ti6Al4V表面改性层的组织形貌和生物摩擦学试验后的磨痕形貌。结果表明:随着喷丸直径的增大,Ti6Al4V表面改性层的表面粗糙度Ra从1.32μm降低到1.05μm,生物摩擦学试验中的摩擦因数呈现出先降低后增大的变化趋势,改性层磨痕的磨损程度呈现出先减轻后加重的变化趋势,但不同直径喷丸二次强化所获得改性层的各项性能在试验中都最差。
