摘      要：Two types of composites were prepared with Al-4.5Cu alloy as a matrix using stir casting *** was reinforced with 10wt.%of Si C and 2wt.%of *** other was reinforced with 10wt.%of Si C and 4wt.%of *** surfaces were remelted using a CO2 laser beam with an objective to study the influence of laser surface melting(LSM).The topography,microhardness,corrosion resistance and wear resistance of the laser melted surfaces were *** surface integrity after LSM was compared with as-cast *** enhanced the microhardness and wear resistance of the surface in each *** of the laser melted surface was low and corrosion resistance was ***,LSM can be conveniently applied to enhancing the surface integrity of the aluminium ***,there is an optimum laser specific energy,around 38 J/m^2 in this study,for obtaining the best surface integrity.
