English Abstract
The present work shows the effect of laser surface hardening process for AZ31B Magnesium Alloy by using a Beam of Fiber Laser.
One sample surface was exposed to a beam of fiber laser with laser parameters of (30 watt peak power, 20 KHz work frequency, and 0.1ms pulse duration) at a fixed wavelength of 1064 nm.
Hardness, roughness, and optical tests for the specimen were examined prior to and following the treatment with laser surface.
Also, it has been indicated that the Hardness and Roughness regarding laser treated specimen were increased when compared to the untreated specimen.
Furthermore, the laser melted surface layer specified enhancement in the significance of microhardness in comparison to the as received (untreated alloy), this is due to grains refining after laser surface hardening treatment.
This research also determines the Characteristic of depth penetration of the surface hardening, and the amount of depth due to fiber laser beam was about (20.8 µm).
