'The microstructure and mechanical properties (hardness and wear resis
tance) of aluminum Alloy 6061 were studied via laser-induced melting,
with SIC particle injection. The upper part of the laser-treated zone
was strongly alloyed, showing a fine microstructure with varied morpho
logy and very high microhardness values (500 HV0.03), compared to the
substrate (60 HV0.03). In the lower part of this zone, SIC particles r
emained completely unreacted and had only mechanical adhesion with the
matrix. Wear tests revealed that extremely high wear resistance (10 t
imes greater than the untreated substrate surface) resulted from this
laser surface treatment technique when a 50-N load was applied.
