The ion implantation technique as a research tool for improving the oxidation behaviour of TiAl-based intermetallic alloys
The effect of various elements added by ion implantation on the isothermal (up to 150 h) and cyclic (up to 1500 h) oxidation behaviour of y-TiAl based intermetallic alloys at 800 and 900 C in air has been discussed. It was concluded that the ion implantation technique can be employed as a screening test for evaluating the effect of possible alloying additions. As a follow up this technique was used as a research tool to study the effect of Nb, Pt, Th, Si, Ta and W on the oxidation behaviour of two types of niobium-bearing TiAl-based intermetallic alloys (Ti-48A1-2Cr-2Nb and Ti-48A1-2Mn-2Nb) at 900 C in air.
