 · Copper-molybdenum composites were formed on nickel substrates. Nickel substrates were cleaned by NaOH at 65°C for 10 minutes, and activated by 10% H 2 SO 4 at room temperature for 1 minute. Copper-molybdenum composites with thickness of approximately 3 μm were electrodeposited using the nickel as a cathode and platinum as an anode.
