Journal of the institution of engineers (India): Series CSummary: Nanocomposite coating plays a significant role in augmenting thermo-mechanical properties when compared with a bare (uncoated) material. There are various methods for the development of nanocomposite coating; however, electrodeposition is one of the methods found suitable due to its controllable parameters and ease of the process. The parameters which can be varied in the electrodeposition process are current density, concentration of electrolyte solution, time, and potential difference. In the present work, Cu-Al2O3 nanocomposite coating has been fabricated on copper substrate using single step electrodeposition technique by varying the potential difference. The present work’s objective is to find out an optimum value of potential difference. For the development of nanocomposite coating, three values of potential difference, i.e., 0.3, 0.6 and 2 V have been selected. Developed coated substrates are characterized by SEM, EDS and FTIR. The microstructure of all these three coated surfaces has changed as compared to bare surface due to potential difference. Moreover, the peak of alumina is found only in the surface coated at 2 V. In addition, surface wettability has been studied using the sessile drop method and ImageJ software. The present research work showed that there is increment in the wettability as compared to the plain copper substrate. The wettability is closely related to the increment in the voltage during the coating process.
