Surface Engineering by Changing the Surface Metallurgy
Improvement in mechanical and tribological properties of functional surfaces of the components using transformation hardening, re-melting, and controlled plastic deformation-based approaches has been presented in this chapter. Rationale behind the change in properties has been discussed in light of metallurgical changes being realized through above approaches. Transformation hardening based methods of surface modification such as flame hardening, induction hardening, laser hardening have been described. Additionally, laser re-melting, burnishing, and shot peening methods of surface modification have also been presented.
