In this paper, the effect of different concentrations of sodium hydroxide on the surface of magnesium alloy plating Ni-B alloys is studied. Focuse on the influence of different NaOH concentrations on electroless plating Ni-B alloy plating rate, coating morphology, and composition. Ascertain the optimal concentration of NaOH. The results showed that when the sodium hydroxide concentration is 50g / L, the deposition rate is the maximum, coating uniformity, structure compact, and boron content in the coating is the maximum.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
