Summary
Aluminium is a metal which is difficult to plate, due to the presence of aluminium oxide which prevents metal to metal bonding. A commercial alloy zincate treatment formed the basis of this work, the main objective of which was to study the morphology and development of the immersion formed film. Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Quantitative image Analysis, were used to examine the process. It has been possible to follow the way in which the film nucleates and grows, to cover the substrate, and elucidate some reasons for the better performance generally claimed in the literature for the double immersion technique.
