摘要
In the present work, Ni-Co alloy coatings were prepared from a modified Watt type electrolyte by direct current. For this purpose, current density was investigated for optimization to obtain high quality coatings on the steel copper substrates. The depositions were controlled to obtain specific thickness (between 50 and 200 mu m). The characterization of the coatings was investigated by scanning electron microscopy and X-ray diffraction facilities. The hardness of the resultant coatings was also measured. The effects of the current density on the tribological properties of Ni-Co coatings were investigated. The results showed that although increasing current density showed increasing coating thickness, the wear resistance of the Ni-Co alloys was decreased due to Co depletion in the deposited layer.
