Study on Al Alloy Surfaces Treated by Ion Beams

Article Preview

Abstract:

Plasma-enhanced ion beams are used for the surface modification of 2024 Al and 7075 Al alloy samples. The morphology of the treated surface of the samples is examined. The corrosion resistance and bending fatigue properties were measured on the treated and untreated samples. The effects of ion beam parameters are discussed. It is indicated that during the ion bombardment, craters are formed and surface melting is produced on the treated surfaces. The effects of ion beam bombardment are limited to the surface layer of samples. With the ion beam energies used in this study, improved corrosion resistance was obtained from the treated surfaces of the samples.
