| Abstract: | In order to obtain Ni-Fe-W alloy coatings with good properties,the effects of pH value,temperature,current density and concentration of sodium citrate on the cathodic current efficiency as well as composition,surface morphology and microhardness of the alloy coatings were studied.Results show that the pH value of electrolyte has a great impact on the coating morphology and cathodic current efficiency as well.The current efficiency decreased with increasing concentration of sodium citrate,while the surface o... |
