Advantages and Properties of Laser-Hardened Surfaces

Abstract:

The paper summarizes the findings of a study of properties and behavior of laser hardened surfaces. The influence of hardening on the service life and tribological resistance of molds and other machine parts will be presented. Furthermore, the influence of process parameters on residual stresses, their direction and magnitude, and related deformation, fatigue behavior under cyclic loading, etc. are described.
