Abstract
Kinetics of cathodic reactions in the ammonia-citrate electrolyte for cobalt-molybdenum alloy deposition is studied using the method of quasi-steady-state polarization curves. The effect of concentration of sodium molybdate on the partial current densities of cobalt and molybdenum deposition is analyzed. The effect of hydrodynamic conditions on the kinetics of cathodic reactions in the cobalt-molybdenum alloy deposition is studied by the method of rotating disk electrode (RDE). In the system under investigation, the dependences of partial current densities of cobalt and molybdenum deposition on the square root of RDE angular velocity are rather complex. The experimental data are discussed under the assumption that various species are adsorbed on the cathode.
