Effect of CeO2 on the Performance of Laser Cladding Coating of Ni-based Alloy

Y. Yang and L. Chen
Abstract—Laser cladding experiments are carried out using the mixed powders with different mass fraction of CeO2. The physical properties of the cladding coating are analyzed, such as the surface morphology, crack sensitivity, dilution rate, wettability, and surface hardness. Further, the influence law of CeO2 on the performance of laser cladding coating is studied. The results show that if the rare earth oxide CeO2 is added into the Ni60A alloy powder, the crack sensitivity of cladding coating can be reduced, and the dilution rate of cladding coating can be decreased, also the hardness of cladding coating can be improved. However, the wettability of substrateit is adversely affected. If the amount of CeO2 is high, the surface quality of cladding coating will decrease, which cannot meet the requirements of application and processing. According to the experiments, it is concluded that the best addition amount of CeO2 is 5%.

Index Terms—CeO2, laser cladding, Ni based alloy, properties of coating.
