Corrosion Behavior of Microwave Clad Material Under Different Acidic Environment

Abstract

The requirement of better functional surface and enhanced product performance has always been thrust for the industrial and academia. The surface modification through microwave energy has been developed and relatively new innovative method for various coatings on the substrate material. The present study involves the hybrid microwave cladding of aluminum and silicon carbide composite in the mild steel substrate at lower cost and processing circumstances. In the present case, pure aluminum and pure Al + 5 wt%SiC were utilized for the cladding over the mild steel substrate material. To investigate the output response, corrosion behavior of the material is tested under two different acidic environments (i.e., sodium chloride and nitric acid). The weight loss measurement is done with the fixed interval of time to know the corrosion behavior of the material. The performance of the clad surface shows the better outcomes compared to the monolithic substrate material. The bonding between the clad and substrate is in excellent accord with the performance improvement as observed by the use of scanning electron microscope.
