| Summary: | Aluminium composites have various applications in engineering thanks to their greater strength with lightweight, formability and ductility. However, the properties of the Aluminium composites such as wear, corrosion, hardness, and fatigue resistance are critical at near-surface regions. In this present research work, the effect on the surface of Aluminium 4.5Cu with Bamboo Leaf Ash composite by laser surface melting was done, wherein the fabrication was done by stir-casting with bamboo leaf ash reinforced particles with 2 and 4 weight percentage. By using the laser machine, the composite’s surface was melted. Microstructure and corrosion behaviour of composites before surface melting and after laser surface melting was inspected and the outcomes were compared. It was perceived that, the diminishment of porosity in the grain refinement. The corrosion resistance of composites had improved remarkably by Laser Surface Melting. The Corrosion mechanism was analysed by observing the morphology of the corroded surface of composites. Henceforth the Laser Surface Melting will be applied appropriately to boost the surface properties of aluminium composites.
