"Shape memory alloys are used in a variety of applications. The area of micro- electro-mechanical systems (MEMS) is a developing field for thin film shape memory alloys for making actuators, valves and pumps.
Until recently thin film shape memory alloys could only be made by rapid solidification or sputtering techniques which have the disadvantage of being “line of sight”. At the University of Missouri-Rolla, electrolytic techniques have been developed that allow the production of shape memory alloys in thin film form. The advantages of this techniques are in-situ, non “line of sight” and the ability to make differing properties of the shape memory alloys from one bath.
This research focused on the electrodeposition of In-Cd shape memory alloys. The primary objective was to characterize the electrodeposited shape memory alloys, while the secondary objective was to produce an optimized shape memory effect for an electrodeposited shape memory alloy. The effect of various operating parameters such as peak current density, temperature, pulsing, substrate and agitation were investigated and discussed. The electrodeposited alloys were characterized by relative shape memory effect, phase transformation, morphology and phases present.
Further tests were performed to optimize the shape memory by the use of a statistically designed experiment. An optimized shape memory effect for an In-Cd alloy is reported for the conditions of the experiments"--Abstract, page iv.
