中文摘要：

采用UMT-2多功能摩擦磨损试验机和电化学工作站（CH1614E）摩擦腐蚀试验平台，考察医用316L不锈钢在模拟体液润滑条件下的摩擦腐蚀行为，利用扫描电镜观察摩擦腐蚀的形貌特征。实验结果表明，316L不锈钢摩擦腐蚀后的腐蚀电位降低，腐蚀电流增大；不同载荷条件下，摩擦腐蚀的摩擦因数均大于纯摩擦下的摩擦因数，且随载荷的增加而减小，摩擦腐蚀电流则随载荷的增加而增大；摩擦腐蚀磨损面的破坏比纯摩擦严重，磨损机制主要表现为犁沟磨损和剪切塑变所造成的局部剥落。

英文摘要：

The tribocorrosion behavior of 316 L stainless steel in simulated body fluid was investigated by UMT-2 multi- functional wear tester and electrochemical workstation （CHI614E）.The morphology of tribocorrosion was analyzed by scanning electron microscopy.The results show that the corrosion potential of 316 L stainless steel after triboeorrosion tests is decreased, but the corrosion current is increased. Under different applied load conditions, the friction coefficient of tribocor- rosion is higher than the pure friction coefficient.With the increase of applied loads, the friction coefficient of tribocorrosion is decreased and the current is increased.The wear surface tion.The main wear mechanism is ploughing wear and damage of tribocorrosion is more serious than that of pure friclocal spalling caused by the shear deformation.
