Development Method for Nickel Electroplating on Aluminium

Abstract

Abstract Aluminum is important material due to high strength/weight ratio. Nickel plating is proposed on luminium for the purpose of improving wear resistance, tribological properties, surface hardness, and decorative appearance. There are number of difficulties when electroplating nickel on luminium is expected. The luminium is amphoteric are soluble in both alkaline and acid. The potential difference between luminium and nickel can affect the deposition reaction due to the diameter and the crystal lattice structure of both different atoms. This study developed nickel electroplating on luminium. Copper and zinc are used as intermediate deposits and final pretreatment coating performed with nickel plating. Interface layers that have been produced are investigated to determine the quality of the nickel layer is obtained.
