In this work, a laminated structure of Cr-Ni coating was prepared using electroplating on carbon steel substrates. Two baths of chrome and nickel electrolyte solutions were prepared to deposit laminated Cr and Ni layers. Chrome was firstly plated on a steel substrate in constant routes whereas nickel was subsequently electroplated on the Cr coating using varied plating times. The effect of Ni plating time on the thickness, hardness and wear specific of the Ni layer was investigated. The results show that an increase of plating times increased the thickness and hardness of the Ni layer, but reduced the wear specific. This study showed that Ni can be a potential candidate as a material replacement for chromium plating maintenance.
