Multilayered microstructure of a Pb–Sn alloy coating obtained by electrochemical deposition

Abstract Electrodeposition is an efficient technique for producing new material with specific chemical and physical properties. These properties stem from the novel morphology and microstructure of deposits. In this paper, we study the morphology and microstructure of the Pb–Sn codeposit by quasi-two-dimensional electrodeposition. A codeposition mechanism is suggested from the analysis by the electrochemical reaction dynamics. Based on this mechanism, the proposal for the microstructure-controlled electrodeposition is offered and an artificial multilayered microstructure is prepared in Pb–Sn alloy system.
