Abstract
TiAl-based intermetallic alloys are being considered as structural mat erials for high-temperature applications due to their low density and substantial mechanical strength at high temperatures. The effect of va rious elements added by ion implantation on the oxidation behaviour of near-gamma Ti-48Al-2Cr and Ti-48Al-2Cr-2Nb (compositions are given in at-%) in air at 800 degrees C has been studied. Ions implanted (10(17 ) ions/cm(2)) were Al, Ti, Cr, Mo, Y, Mn, Pt, Nb, and Si in case of Ti -48Al-2Cr and Nb in case of Ti-48Al-2Cr-2Nb. Comparison was made with the oxidation behaviour of Ti-48Al-2Cr-2Nb and Ti-47Al-2Cr-0.2Si alloy s in which quaternary elements were added by alloying. It is concluded that ion implantation can serve as a research tool to study, in the f rame of screening tests, the influence of various elements on the corr osion behaviour of materials.
