The receiving method and some properties of the composite nickel containing galvanic coating on base nickel-cobalt-oxide silicon-carbide silicon system were discussed. Chloride electrolyte for the application of the composite electroplating coating with firmness to wear and corrosion properties of nickel-cobalt-oxide silicon-carbide silicon system was elaborated. Influence of electrolysis and electrolyte composition on physico-mechanical properties (firmness to wear, corrosion resistance, hardness, internal tensions, porosity, adhesion) of the composite electrolytic coating of nickel-cobalt-silicon oxide system, electroplated from chloride electrolyte, and on the properties of electrolyte (diffusing ability, output current draught) were investigated. The possibility of using for composite electroplating of nickel-cobalt-silicon oxide-carbide silicon system as a firmness to wear coating in instead of chrome was showed.

Ni-P diamond particles (20μm) composite coating on friction shims were prepared by electroless plating. Morphology and phase composition of the composite coating were measured by SEM with EDS and XRD. The friction coefficient of the coating was test with scratch test. The results showed that diamond particles distribution was uniform and not stacked by two steps for 10 min. The diamond particles were half embedded in the Ni-P substrate. The element of the coating was Ni,P,C and the phase composition was Ni and diamond. Adhesion of the composite coating was higher than that of the Ni-P coating. Friction coefficients of the Ni-P coating and Ni-P composite coating were 0.47 and 0.18. Half –naked diamond particles played a pinning role and prevented from wear of the coating to get the big friction coefficient and good wear resistance. This Ni-P composite coating on friction shims would improve friction shims technology and realize the production of localization of friction shims.

iamond cutting wire, as a new one, could overcome the defects of traditional cutting wire and would have a wide potential application. Electroplating diamond wire was prepared by composite electroplating in this article. The influence of cathodic current density, the diamond content in the electrolyte and other process conditions on the amount of diamond in the composite coating was checked by EDTA titration analysis. Effects of the diamond content in the electrolyte on electrochemical process of copper-diamond composite electro-deposition were investigated by measuring electrochemical polarization curves. With increasing the cathode current density and the diamond content in the electrolyte, the amount of diamond in the composite increased firstly, and reached a maximum, then decreased. The cathode current decreased with the increase of diamond content in the electrolyte. Copper-diamond composite plating process could be explained by Guglielmi two-step adsorption mechanism. The influence of plating parameters on the deposition behaviors of copper–diamond composite coating layers is ascribe to the change of diamond adsorption state on the cathode surface. After heat treatment, the largest wire tensile force is 159.7 N and the tensile strength reaches to 2258.8 MP.
