Effect of Pulse Electroplating Parameters on the Deposition of Reinforcing Particles in Ni-W/CeO2 Composite Coating

Recently, nickel-tungsten (Ni-W) coatings have been investigated by many researchers as a corrosion-resistant, wear-resistant, and high-hardness layer. However, reinforcing particles is also used to form composite improve the performance of these coatings. Therefore, in this research work, Ni-W coating reinforced with CeO2 was formed electroplating method pulse current on pure copper metal. The microstructure, chemical composition, thickness applied were using field emission scanning electron microscope (FESEM). X-ray diffraction (XRD) determine phases coating. effect parameters plating process, including duty cycle, frequency, waveform co-precipitation matrix. results showed that increasing cycle up 70%, frequency 100 Hz, pulsed square wave shape caused more deposit Under optimal conditions, uniform distribution particles, thickness, very good adhesion substrate.
