Abstract Electrochemical techniques were used to investigate the erosion-corrosion of titanium in simulated acidic mineral leaching slurries. Erosion-corrosion of titanium was caused by solid particle impingement. Electrochemical noise revealed that solid particle impacts resulted in localised fracture of the passive film, and erosion-corrosion of titanium proceeded in the form of current transients. As conditions become more abrasive, erosion-corrosion is an increasing threat to titanium equipment exposed to acidic slurries.

钛在模拟酸性湿法冶金泥浆中侵蚀腐蚀过程中的局部不稳定性

摘要 采用电化学技术研究了模拟酸性矿物浸出液中钛的冲刷腐蚀。钛的侵蚀腐蚀是由固体颗粒撞击引起的。电化学噪声表明，固体颗粒撞击导致钝化膜局部断裂，钛的侵蚀腐蚀以电流瞬变的形式进行。随着条件变得更加磨蚀，侵蚀腐蚀对暴露于酸性浆料的钛设备的威胁越来越大。
