摘要：

The corrosion rate, wear rate, corrosion wear rate, variation of Vickers hardness of the worn surface, and the recovery time of passive film were determined for alpha- + gamma duplex stainless steel (DSS) in sulfuric acid (H2SO4) or H2SO4 + sodium chloride (NaCl) solution. In the chloride (Cl-) solution, the wear-induced corrosion and the corrosion-induced wear were approximately 4% and 70% of the total damage, respectively. Damage was less in the absence of Cl-. Morphologies of tracks and debris also were observed. Results showed Cl- embrittled the worn surface of the metal.
