Corrosion Behavior of AISI 4140 Steel Surface Coated by Physical Vapor Deposition It is obvious that the corrosion rate decreases as the pH of solution increases. The highest corrosion rate is observed at pH 2 because the solution was adjusted by HCl acid that significantly increased chloride (Cl-) ion and hydrogen ion (H+) in the solution.
