Improved high temperature oxidation behaviour of alloys by ion implantation

Abstract

Numerous studies have been undertaken during the last decade examining the potential of ion implantation to improve the high temperature oxidation behaviour of a range of metals and alloys. Most of these investigations have focussed on improved mechanistic understanding of the role of specific elements and, in particular, of the effect of the so-called reactive elements, such as yttrium and the rare earths. It is now apparent that the ionimplantation studies have made a unique contribution and these will be reviewed.
