Electrodeposition of Ni-Based Coatings with the Addition of CeO2 Nano Particles

In the present study, a new nanocomposite coatings, Ni-CeO2, has been prepared by electrodepositing. The effect of current density on the CeO2 particles included into the deposits, morphology, preferred orientation, wear resistance and high temperature oxidation resistance has been studied. The investigated results demonstrate that the weight percent of particles in the nanocomposite coatings varied with a rise in current density, and the maximum weight percent of CeO2 particles in the coatings is 4.97 wt% obtained at the current density of 1 Adm-2. The paper firstly presents that the high temperature oxidation resistance of nanocomposite coatings is closely related to the current density, at which the nanocomposite coatings were electrodeposited, and the best high temperature oxidation resistance was acquired at the current density of 1 Adm-2
