Complexation effects in the electrodeposition of nickel-iron alloys
- Univ. of Tulsa, OK (United States)
The nickel-iron alloy electrodeposition system exhibits a phenomenon known as anomalous codeposition, where the less noble metal (Fe) deposits preferentially to the more noble metal (Ni). One explanation for this behavior is that ferrous hydroxide adsorbs to the surface of the electrode and inhibits the electrodeposition of the nickel. This mechanism is being tested through the use of {open_quotes}selective{close_quotes} complexing agents for Ni{sup 2+}, Fe{sup 2+} and Fe{sup 3+}. The complexation behavior of these ions with acetate, chloroacetate,and aminoacetate ions is being characterized by potentiometric titration and polarographic measurements. The effect of these complexants on the electrodeposition of the alloys is also being studied.
