Abstract

Laser assisted surface modification has been used to produce variety of surface/sub-surface microstructures in AZ91 alloy. Refined microstructures thus produced have been characterized by metallography. Electrochemical corrosion behaviour of these variations is studied using polarization carves and compared to that of sand-cast alloy. Scanning electron microscope is used to determine post corrosion morphology. The corrosion behaviour is correlated to refined microstructures developed upon laser treatment.
