✦ Synopsis

other unique feature was the ability to introduce Numerous studies have been undertaken during into this surface layer controlled concentrations of most elements. Implantation of an element the last decade examining the potential of ion affected high temperature oxidation in a cornimplantation to improve the high temperature oxidation behaviour of a range of metals and alloys, parable manner to an alloy addition [3, 4]. Pre-Most of these investigations have focussed on cisely because of its unique features, ion implantation established that the dramatic influimproved mechanistic understanding of the role of ence of many elements derived from their incorspecific elements and, in particular, of the effect of poration into the oxide scale during the early the so-called reactive elements, such as yttrium and the rare earths. It is now apparent that the ionstages of oxidation [1, 3].

Therefore, what became clear from these implantation studies have made a unique contribution and these will be reviewed, initial studies was that ion implantation was an important procedure for studying the mechanisms underlying the crucial and dominating role
