Rapid Fabrication of Cu-Al₂O₃ Nanocomposition Coatings

Abstract:

A jet electrodeposition device was carried out to prepare Cu-Al₂O₃ nanocomposite coatings. The influence of the concentration of Al₂O₃ in the electrolyte and parameters on the content of the Al₂O₃ in the deposite were investigated. The coatings ingredient and microstructure was measured by the scanning electron microscope, the microhardness tests were conducted on an microhardness tester. The results show that the copper deposited layers have nanocrystalline microstructure with grain size of about 50nm . The amount of Al₂O₃ in composites first increased and then decreased with an increase in the concentration of Al₂O₃, current density, temperature and jet velocity. The composite with optimum atomic percent of Al₂O₃ (14.4 at%) can be obtained at the concentration of 30 g/l , cathodic current densities 300 A/dm², temperature 30°С , and jet velocity 8 m/s . The addition of Al2O3 in copper increases the microhardness of the electrodeposited coatings.
