The laser surface alloying for metallic materials has been applied widely to improve the wear resistance, corrosion resistance and other required properties. The studies of laser surface alloying on copper-base materials are becoming more and more important. This work using two methods of pretreated coatings, i.e., chemical bonded 50%Cr-50%Cu and pure Cr powders and electroplating chromium coating respectively, on pure copper substrate surface to prepare laser alloyed Cu-Cr alloy coatings was investigated. The samples were treated with different laser scanning speed. Using scanning electron microscopy (SEM), micro-hardness indentor and wear tester, the effects of different coating processing parameters on the microstructure and properties of Cu-Cr coatings were determined and analyzed respectively.
