Laser-based surface modification is an advanced materials engineering process widely used to enhance the surface characteristics of engineering alloys. This technique employs high-energy laser beams to alter the microstructure and composition of alloy surfaces, resulting in improved wear resistance, corrosion resistance, hardness, and fatigue life. This paper delves into the principles, methods, benefits, and applications of laser surface modification (LSM), including laser hardening, alloying, cladding, remelting, and texturing. It also explores current research, challenges, and future directions in this technologically evolving domain.
