| Abstract: |
| For higher hardenability, H13 is important industrial steel and is used for producing all kinds of hot dies. The service life of hot dies is low because of several physical and chemical actions during the service. Several surface strengthening techniques improving the service life of H13 die steel were introduced. Multi-penetration, complex treatment and plasma immersion ion implantation are very effective methods to improve the surface properties of H13 steel as compared to laser surface strengthening. Laser surface strengthening, to some extent, was limited in application because of many factors during treatment, expensive facilities and simple work-piece treated. |
