Abstract
This is a critical review of the research work on the effects of high power beam surface modification techniques on corrosion wear and fatigue properties of modified materials, published in literature during the last 5 years. In general terms, highly adherent surface alloys were produced on irons, steels, stainless steels, Ti-base alloys, Cu and Al alloys using either ion beam, electron beam or laser beam. Many surface alloys produced by ion beam, electron beam and laser beam when produced under favourable conditions of treatment appeared to have better resistance to corrosion and/or wear than the original materials. There is a large number of process variables, however, that influence the properties of modified layers which makes the process design difficult.
