Abstract
The corrosive wear behavior of high-alloy stainless steels (SS) under sliding conditions was investigated in 20 wt% sulfuric acid (H2SO4) solution. Experiments showed a negative shift of the corrosion potential, positive shift of critical passivation potential, and steady passivation potential could be regarded as accelerative effects of wear on corrosion. For 18-8 austenitic SS (UNS S30302), it was concluded that the accelerative effect of wear on corrosion increased with increases of the corrosion rate.
