Surface Roughness of Laser Modified Die Surface Change Under Thermal Cyclic Loading

Thermal fatigue crack results in decrease of die service life has brought to a significant loss in the die casting industry due to the high cost of die. Laser surface modification is proposed in this study to enhance the surface properties of die and increase the resistance of thermal crack. In this...
