The Enhancement of the Corrosion Protection of 304 Stainless Steel using Al_2O_3 Films by PLD Method

摘要

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.
