研究了微动腐蚀对管柱水泥界面内岩屑降解和形成的影响。电化学测量电位和极化电阻，以及溶液质谱。利用光学、扫描电子和透射电子显微镜以及能量色散x射线光谱学技术观察微动腐蚀试验后的表面形貌。电化学测量表明，动态载荷导致金属表面钝化。溶液质谱分析表明，界面释放出高浓度的钴离子，占释放到环境中的所有金属离子的94%。微动腐蚀产物的详细图像表明，由于微动腐蚀释放的物质具有电化学稳定性，金属和骨水泥表面形成了一层铬和氧层。
The role fretting-corrosion plays on the degradation and formation of debris within the stem cement interface was investigated. Electrochemical measurements of potential and polarisation resistance, along with solution mass spectroscopy were employed. Optical, Scanning Electron and Transmission Electron Microscopy with Energy Dispersive X-Ray Spectroscopy techniques were utilised to observe surface morphology after fretting-corrosion tests. Electrochemical measurements indicated dynamic loading resulted in de-passivation of the metallic surface. Solution mass spectroscopy indicted high concentrations of cobalt were released from the interface, accounting for 94% of all metallic ions released into the environment. Detailed imagery of fretting-corrosion product indicated a chromium and oxygen layer on the metallic and bone cement surface owing to the electrochemical stability of species released as a result of fretting-corrosion.
