INTERACTION BETWEEN CORROSION AND WEAR OF STA LESS STEEL IN H_3PO_4+NaCl SOLUTION

Plots of corrosion-wear loss vs load and anodic polarization curves during wearing were for a duplex stainless steel in 69% H_3PO_4 solution with or without Cl~- by a pin-on-disc apparatus.Morphologies of tracks and debris as well as variation of Vicker hardness of worn surface were also examined.The Cl~- may impel the embrittlement and tear of worn surface,so as to accelerate the corrosi-wear loss of the steel.
