Effect of Severe Plastic Deformation, through Equal-Channel Angular Press Processing, on the Electrochemical Behavior of Al5083 Alloy
Source abstract
Abstract
In this study, Al5083 alloy was deformed through equal-channel angular pressing (ECAP) up to three passes. The ECAP was conducted at room temperature in a mold using route C. The microstructure evolution was investigated under optical microscopic observations. The grain size was measured using ImageJ software. Grain refinement from 145 µM (as received) to 37 µM (after third pass) was observed due to ECAP. The potentiodynamic polarization of the Al5083 alloy was obtained from a 3.5% sodium chloride solution. Electrochemical impedance spectroscopy was performed in the sodium chloride solution to study the alloy’s surface properties. Scanning electron microscopy and Raman spectroscopy were conducted after obtaining the corrosion performance. As a result, we found that ECAP processing leads to the grain refinement of the alloy, which causes a detrimental effect on the corrosion resistance property.
