Abstract

In this paper, we have studied the effect of controlled parameters on the anomalous behavior and property of the codeposited nickel-cobalt (Ni-Co) films in the complex sulfamate-chloride bath. The variation of current densities and temperature resulted in different Co atomic percentage (Co at%) of the deposited films as well as the morphology and microhardness. Co at% in Ni-Co films gradually decreased with increasing current density and temperatures with variation from approximately 25 to 15%. The Co participation could also inhibit grain growth of the deposited films. The Ni-Co film codeposited at lower current density or temperature would have the higher hard Co content and smaller grain which results in the higher microharness and smooth morphology.
