The Influence of GGG70L Laser Surface Hardening Power on Quenched Layer Performance

Abstract

GGG70L die material laser phase change hardening aims to discover the Quenched Layer performance of the GGG70L die material hardened by the laser of different power. Making comparison and analysis in the experiment and considering the actual production factors such as cost, working efficiency and product quality standard, it is concluded that laser power being 1900 w, laser scanning speed 6mm/s, spot size 3×15 mm2, focal length being 305mm, the surface of the material quality can meet the requirements of industrial production, laser surface quenched layer becomes harder, good abrasion resistance on the surface of the material is obtained.
