Study the Corrosion and Wear properties of Al-12.5Si-3.5Cu alloy in the acidic and basic environments

Abstract

This research involves study the polarization behavior of Al-Si-Cu alloy in acidic and basic medium ( 0.1 M HCl & 2.5x10- 3 M NaOH) by potentiostatic method and the values of Tafel slopes (b) ,corrosion rate (Rmpy) and the polarization resistances (Rp) were interpreted. Wear properties for this alloy in acidic and basic medium were measured at different sliding speed and different applied load and gives same results that observed in the corrosion behavior.
