Investigating the Effects of Fiber Laser Surface Treatment on the Hardness and Machinability of 316L and Ti-Zr Implant alloys manufactured through powder metallurgy

Abstract

A high-power fibre laser is used to the alloy surfaces as part of the experimental methods to cause controlled microstructural alterations. Comprehensive investigations are then carried out to determine how the laser treatment has affected the material's properties. These analyses include microhardness testing and machinability assessments. The outcomes show significant improvements in both alloys' hardness and machinability, suggesting that fibre laser surface treatment is a feasible method for enhancing the mechanical properties of implant materials made via powder metallurgy. The results of this investigation provide significant contributions to the design and manufacturing processes of implant alloys, with potential to enhance the long-term stability and functionality of biomedical implants.
