摘要：

To improve the service performance of roller. The surface of roller was alloyed by a 5kW CO2 laser. The effect of CeO2 on microstructure and hardness was studied by means of OM, Micro-hardness Testing Machine and Rockwell hardness tester. The results indicate that addition of CeO2 into coating materials can enhance the fluidity of molten liquid, refine and purify microstructure and increase microhardness and surface hardness of alloying coating.
