Localised instability of titanium during its erosion-corrosion in simulated acidic hydrometallurgical slurries

Liu, Yu; Alfantazi, Akram; Schaller, Rebecca S.; Asselin, Edouard

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.
