Abstract :
Samples of C62500 aluminum bronze were treated by a continuous wave CO2 laser to rapidly melt and quench the surface. This processing transformed the surface layer from multiphase 
primary and secondary iron-rich δ to homogeneous, supersaturated single-phase 
solid solution. The cavitation erosion resistance of the laser quenched material far surpassed that of untreated C62500. The physically detrimental effect of the processing, i.e., roughening of the surface, appears to have been overridden by the positive microstructural changes in the surface layer.
