Description
Summary:Laser surface hardening is an efficient method used to enhance the tribological properties and increase the product life of mechanical components used in various engineering industries. This project report comprises the laser hardening simulation of materials EN8 and EN24 Steel using ANSYS 2020 R2 ACADEMIC simulation software. This study aims to determine the optimum scanning speeds required for martensitic transformation to occur in the materials EN8 and EN24 at varying power levels. As the power intensity of the laser increases the surface temperature, the surface of the material reaches its austenitic state and is cooled rapidly causing the material to harden. The martensite formation is observed by studying the temperature profile corresponding to the surface temperatures of the material at each iteration of the simulation. Each iteration was simulated by varying the laser power and laser scanning speed and by keeping the laser beam diameter constant. The results were further analyzed and the iteration corresponding to the desired output were selected.
