    • Abstract

       

      Rapid electrodeposition is economically a valuable way that has led to the invention of different methods. In this study, rapid Zn–Ni ${\gamma}$-phase electrodeposition from modified Watt’s bath containing zinc ions was investigated. A high current density was applied in assistance with the turbulent fluid flow as a simple technique for rapid electrodeposition, and the influence of saccharin amount was investigated on microstructure and corrosion resistance of rapid electrodeposited films. Rapid electrodeposition led to the formation of a preferred texture orientation of (600) and a small crystallite colony size. Structural changes and variation in the composition of rapid electrodeposited ${\gamma}$-phase resulted in improved corrosion resistance. The addition of saccharin into the electrolyte altered the preferred crystal texture to (300) and increased the crystallite colony size, accompanied by changing diamond-like morphology to the faceted surface and inhibited formation of microcracks that were detected in rapid electrodeposited films.
