Surface hardening, also known as surface heat treatment, includes transformation hardening and shock hardening. Transformation hardening is a heat-treatment process by high-power laser beam irradiation on the surface of metals and other materials. The temperature of the heated material reaches the phase transition point, but melting does not occur. After the end of the laser pulse, the metal
Due to the case hardening heat treatment process, the low-carbon steel (up to 0.25 percent carbon) produces a hard, wear-resistant surface. Medium-carbon steel The medium-carbon steels (0.25 to 0.55 % of carbon) are generally produced by through-hardening & tempering process which provides higher tensile strength ranging from 690 to 1380 MPa. Due to the lower strength of low carbon steels
