Electrodeposition of alloys XV: Electrodeposition and x-ray structure of Bi-In alloys

Abstract

Bi-In alloys containing up to 90% In were electrodeposited from aqueous solutions containing the diethylenetriaminepentaacetate ion as the complexing agent. An increase in the current density and the indium content of the bath decreased the percentage of bismuth in the deposit. The current efficiency decreased with increasing current density but was not significantly affected by a change in the indium content of the bath. Deposits containing 63%–89% In were of good visual quality and offer promise as a decorative finish. The X-ray phase structure of the deposited alloys is reported.
