Effect of Different Contents of CeO₂ on Microstructure and Properties of Roller Surface Alloyed by Laser

Abstract:

To improve the service life of roller, a kind of alloying powder materials with CeO2 was designed. And the surface of roller was alloyed by a 5kW CO2 laser. The effect of CeO2 on microstructure and properties was studied by means of OM, Micro-hardness Testing Machine, Friction and Wear Tester. The experimental results indicate that addition of CeO2 into coating materials can refine and purify microstructure. Microstructure in alloying layer is coarse without CeO2, when CeO2 is up to 2.0wt.%, microstructure in alloying layer becomes finest. And microhardness and wear resistance become largest.
