Abstract:

Article Preview

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.
