The enhancement of the corrosion protection of 304 stainless steel using Al2O3 films by PLD method

Abstract

In this manuscript, we are using LSP to reduce the corrosion rate of stainless steel 304 in hydrochloric acid with the concentration of 1 M and the immersion time of 5 minutes at room temperature. The method was used to conduct the corrosion measurements is the polarization method, where the corrosion rate reduced from (CR=78.971mm/y) to (CR=5.217mm/y) at the optimum results DDDW=4mm, E=900mj & no. of pulse =250, we were found the efficiency= 93.39%. The synthesized samples were analyzed utilizing XRF, Tafel test, EIS, and the microhardness measurement.
