Abstract
The inadequate wear resistance and hardness of SS 316L make it unsuitable for use in harsh mechanical conditions. The present study reports the deployment of powder bed fusion (PBF) to create B4C particle-reinforced SS 316L composites to improve the mechanical properties of SS 316L. The study focuses on the influence of PBF process parameters on the track width (TW), track depth (TD), surface morphology, hardness, and surface roughness of a single track. TW and TD both increase with laser power (LP). The maximum hardness of 328 HV and minimum surface roughness of 0.07 µm are seen at LP of 300 W, and laser travel speed of 0.06 m/min. The absence of B4C particles is noticed at high laser powers due to the low density of reinforcement particles.
