“…laser beam and composite materials surfaces, many laser technologies have been established such as laser heattreatment, laser surface alloying (LSA), cladding and laser surface melting (LSM). Surface melted by LSM produced a refine microstructure that minimized the size and sites of the galvanic couples for pits nucleation [6]. LSM involves the application of short, high power pulses to melt the surface of the material, which then rapidly solidifies.…”

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.

“…In recent years there have been reports on the effect of surface laser treatment on aluminium and its alloys [11][12][13] and composites, with a particular focus on Al 18 B 4 O 33 -reinforced [14,15] and SiC-reinforced systems [9,10,[16][17][18]. Additional information on the effect of laser treatment of these materials can be deduced from research activities on laser welding [19][20][21].…”
