|Abstract:||In this study, we evaluated the influence of nickel and cobalt concentrations in an electrochemical bath for a ternary Ni‐Co‐W coating alloy electrodeposition. The X‐ray diffraction indicated formation of amorphous coating alloys for higher Co concentration and a crystalline coating alloys for higher Ni concentration. Statistical evaluation showed a mathematical model connecting the increase of alloy deposition efficiency and the Ni and Co concentration in the electrochemical bath. Corrosion tests indicated that coating alloys with higher Ni concentration, which are crystalline alloys, showed higher polarization resistance (in NaCl 0.1 mol/L) indicating that composition can influence the corrosion resistance more than the crystallinity|
