Characteristics of Thin Metal Plate Being Strengthened by Laser Irradiation

Abstract:

The general method for strengthening the surface hardness is known to be heat treatment by means of the laser. Generally, the smaller and the lighter component is hopefully used for parts of machine or complicate structure. Hence, Instead of a heavy structure, a thin panel with sub structure or engraving the grooves or waving on that is used. It is noted well that those processes make an original structure strengthened. Therefore it is expected that the thin plate panel can be much more strengthened and stable through processing of the metal surface by laser beam irradiation. Through this research, it would be explained empirically how the hardness be changed and mechanical characteristic changed by width and depth of groove by laser affect. As of conclusions, the structural characteristics of a thin plate being strengthened locally by laser irradiation will be presented in comparison with the results obtained from FEA analysis
