Laser Hardening

A Brief Introduction

Laser hardening is a surface treatment process that enhances the hardness and wear resistance of metals. It involves focusing a high-intensity laser beam onto specific areas of a material, rapidly heating and then quickly cooling them. This controlled thermal cycle modifies the microstructure of the surface, creating a hardened layer that improves durability without affecting the material’s core properties. Laser hardening is widely used in industrial applications, such as strengthening metal components in automotive and tool manufacturing, resulting in enhanced performance and longevity.

Projects

Gasket Die Laser Hardening The Gasket Die Laser Hardening project aimed to enhance the wear resistance of gasket dies used in plate heat exchanger’s sealing gaskets production. Utilizing laser beam technology, we navigated the challenge of hardening the edges for improved durability without compromising ductility. Extensive experiments, guided by optimal parameters, successfully increased the hardness of the die’s narrow edges, promising a doubled lifespan. This innovative approach, avoiding the need for post-machining, signifies a significant advancement ...
