The Effect of Complexing agent on the Surface of Aluminum Alloy Plating Ni- P Alloy

摘要

In this paper, the effect of different concentrations of complexing agent on the surface of aluminum alloy plating Ni-P alloys is studied. Study the influence of malic acid complexing agents on the electroless Ni-P alloy deposition rate, morphology, corrosion resistance, and determine the optimal complexing agent concentration. The results show that when the malic acid concentration is 24g/L, the deposition rate gets to maximum, and coating uniformity, structure compact and corrosion resistance is best.
