| Abstract | ||
| The surface treatment of the carbon steel is important for the improvement of its properties, which lead to the improvement the efficiency during the operation. The laser surface hardening is a new technique, which used the incident laser beam upon the surface of metal to cuse local heating and slef quenching result from the effect of the beam.There is many application in the experimental and industrial of the laser technique because of the converging the laser beam by the lens on a very small spot which its diameter near the value of the laser wave length. This lead to concentrate high energy in very small area which lead to high heating in comparison with the usual heating sources which give lower heating energy density produced by the traditional heating sources. As an example of solid state laser such as Ruby laser, Nd-Yag laser, Nd-glass laser and CO2 laser, each type of these has properties, which determined the applied field.In this paper Nd- glass laser has been used to surface hardening of low carbon steel, which study the irradiation and its effect upon microstructure, surface hardening and wear resistant of the metal. | ||
