Effect of Addition Some Element Laser Surface Treatment on Wear Rate of Al-16%Si
Engineering and Technology Journal,
2011, Volume 29, Issue 7, Pages 345-356
AbstractIn this work laser surface treatment has used in hardening alloy which are (Al-
16%Si) after melting it and addition element which are (Mg,Cu,Ni) with high
purity with suitable quantities by using pulsed Nd-Glass laser with pulsed duration
(6Hz.) with overlapped-pulses.laser surface melting method done for the alloy,and
wearing test performed with different loads before and after laser treatment ,the
results show that wear rete and hardness increases after laser treatment.
Keywords: high purity, Nd-Glass laser, laser surface melting, wear, hardness.
