Abstract

The effects of organic additive, 3-amino-5-mercaptoI, 2,4-triazole (AMTA) on bath stability, deposition rate, reaction activation energy, and Ni-P coating composition in acidic electroless nickel plating were investigated.Polarization curve method and infrared reflection spectroscopy were used to analyze the mechanism of the effect of AMTA on electroless nickel deposition. It was observed that AMTA improved bath stability, decreased the deposition rate, and increased the reaction activation energy. It was also revealed that AMTA decreased the phosphonrs content and increased the sulfur content in Ni-P coating. In addition, AMTA inhibited the anodic oxidation of hypophosphite and accelerated the cathodic reduction of Ni²⁺ Infrared reflection spectroscopy result indicates that AMTA was adsorbed on the surface of Ni-P and interacted with Ni²⁺ to form an AMTA-Ni²⁺ compound. On the basis of the results of this study, the mechanism of the effect of AMTA on electroless nickel deposition was deduced.
