A Ni-B coating was electroless-deposited directly on acetic acid pickled AZ91D. The plating rate was found to be influenced by pH, temperature, and bath composition. The electroless Ni-B plating exhibits a uniform surface and an amorphous structure. Polarization curve and electrochemical impedance spectroscopy measurements in 3.5 wt.% sodium chloride aqueous solution suggest that the plating can protect the magnesium alloy substrate from corrosion attack. It is proposed that different deposition reactions dominate in different stages of the plating process. (C) 2012 Elsevier B.V. All rights reserved.
