Abstract

In materials science and engineering field, different materials design concepts such as general conventional (one alloy-at-a-time) approach and recent combinatorial (multiple-sample approach) approach are being used to understand, discover, optimize and develop highly tailored, formulated materials with intricate structure and behavior to improve the properties for a specific application. In contrast to conventional approach, a new scientific scheme called combinatorial approach is used in the present study because it enables to generate composition gradient libraries of materials systems within a single synthesis experiment. The combination of the combinatorial approach and high-throughput characterization techniques allow for fast identification of the best composition for specific applications. Till now, mostly vacuum-based thin film fabrication technologies (sputtering, pulsed laser deposition), have been used to fabricate combinatorial materials libraries, which are very expensive, complex and slow. In the present study, an alternative cost-effective technique, electrodeposition (in a modified Hull cell) with its relatively simple setup is used for fabricating materials libraries. Previously, few attempts have been made to generate alloys with composition gradients in modified Hull cell through electrodeposition. And also, no models are available to describe the electrodeposition process of single metals and alloys in the modified Hull cell.
