Abstract: This article presents our experimental procedure for the surface alloying of the 45 steel by a GW CO2 laser with various scanning speeds. After laser alloying treatment, the alloyed layer has been synthetically analysed on the distribution of elements in the alloyed layer, microstructure, distribution of hardness and wear resistance of the alloyed layer. The relation between the structures, properties of alloyed layer and laser scanning speeds has been presented.
