The use of lasers has become a significant source and splendid tool for various surface modifications. Laser surface melting offers extensive promises to accomplish preferred surface properties. The surface is melted by laser irradiation and cooled rapidly by self-quench procedures and is widely utilized as a research tool. The homogeneity of the surface chemical composition is refined and changed by adding other materials in this process. After surface modifications, microstructural changes, corrosion, erosion, and wear properties of different alloys are explained widely in this chapter. The possibilities of repairing the stress corrosion cracking and intergranular corrosion behavior also addressed the effect of heat treatment techniques on stress relief and strengthening of the mechanism of surface treatments.
