| Abstract: | The electrodeposition of Ni-La-P alloy from aqueous solutions of citric acid,phosphorous acid and ammonium chloride has been studied by linear sweep voltammetry. The electroplating potentials of the metallic ions were found shifted to positive region in the presence of complexing agent and phosphorous acid and the Ni2 ions were favorable for induction of deposition. XPS records indicated the alloy's composition mass fraction as Ni 92, La 2. 15, and P 5. 85. |
