Abstract
In this study, Ni-P-MWNTs composite coating was successfully deposited on the surface of AZ31 magnesium alloys by electroless plating. The electrochemical properties of the composite coatings were studied by electrochemical workstation system. The corrosion behavior of the composite coatings was evaluated by polarization curves in 3.5 wt% NaCl aqueous solution at room temperature. Its corrosion resistance was improved significantly than AZ31 magnesium alloys. The wear behavior of the coatings was investigated using friction and wear test method. The results indicated that the incorporation of carbon nanotubes in the coating improved both tribological behavior and corrosion resistance. Comparing with Ni-P coating, Ni-P-MWNTs composite coatings showed not only higher wear resistance but also lower friction coefficient. These improvements have been attributed to superior mechanical properties, unique topological structure and high chemical stability of nanotubes.
