Composite Ni-Co-fly ash coatings on 5083 aluminium alloy

▶ This research investigation focuses on a study of the surface technological properties of an electrodeposited Ni-Co-fly ash composite coating on zincate treated 5083 aluminium alloy substrate. Up to date, very few research articles have been reported on the correlation between microstructure and corrosion behaviour of complex metal matrix composite coatings on engineering alloys. Finally, this research study aims in expanding the technological application of massive fly ash produced in power stations on the important field of coatings technology. It is believed that in several cases fly ash might possibly replace other expensive commercial oxides.
