| Popis: |
Laser hardening of metal alloy provides the economical avenue to achieve high-performing surfaces. Complexities in geometrics and hard-to-reach surfaces can be easily handled with this process. Heterogeneous materials such as cast iron pose a challenge to achieve targeted surface properties using laser hardening. It is still one of the most important materials being used in the automotive industry due to its castability, machinability, and damping. Cast iron also has better frictional performance and wear resistance. Its wear performance can further be enhanced using laser hardening. In the current investigation, 400 W optic fiber laser system was employed to study the effect of process parameters on the selective surface area by laser hardening. The laser beam power and laser scanning speed with constant laser beam diameter were used for the surface scan. Surface properties such as micro-structure and hardness were studied. It was observed that micro-hardness was double compared to the untreated surface. |
