Engineering and Technology Journal, 2011, Volume 29, Issue 14, Pages 3006-3018

In this research, a pulsed Nd:YAG laser with wavelength (1064nm )
and (532 nm) and pulse duration (100 ns) for different energies [250 mJ,500 mJ,750 mJ,1000 mJ ] and spot size (1.5mm) was used.
Laser surface treatment is the most important way in industrial application because of its ability to improve the surface properties of metal and alloys. The alloys used were [Al-Cu-Si], [Al-Si-Mg] and [AL-Zn-Mg].The essential aim for this work includes study the effect of laser parameters on aluminum alloys. In laser surface engineering the mirohardness and wear tests will be studied after laser treatment.
The effect of laser parameters includes:
1- The effect of the pulsed Nd: YAG laser energy.
2- The effect of the number of shots (pulse).
