摘要：

Commercial pure aluminium was laser surface alloyed with nickel using an Nd-YAG pulse laser. It was observed that the roughness of the alloyed surface decreased with an increase in the extent of defocusing of the laser beam. The observation is explained in terms of the variation in laser power density due to defocusing, and the concentration of the alloying element in the alloyed layer.
