In this study, laser surface hardening process was
applied to the 8620 steel which is used in the parts, for the
machines and automobiles, gear wheels, pins and shaft enamel.
Laser power and laser feed rate were determined as laser surface
hardening parameters. It has been studied between 1050 and 1400
W as laser power. 4 and 6 mm velocities were preferred as the feed
rate. The hardness of the samples was measured under 500 g
(HV0,5) load for 15 seconds. Nikon brand optical microscope is
used for microstructure studies. According to the hardness results,
the hardness of hardness of 8620 steel was obtained with 1400 W
laser force and 6 mm feed speed.
