Beschreibung:
<jats:p>The effect of Mo on the oxidation behavior of TiNiAl at 1073K has been investigated. It is
found that 1at.% Mo addition can increase the diffusion of Al in the alloys and promote the formation
of dense and continuous Al-rich oxide layer. Therefore the oxygen diffusion can be effectively
impeded and the oxidation behavior of TiNiAl is improved. The observation of the cross-sectional
oxidation layer showed that beneath the top oxide scale a Mo-rich oxide layer formed. Because the
oxide of Mo is volatile at high temperature, voids formed in the oxide scales during the oxidation
process. 3at.% Mo addition could cause cracks between the oxide scale and the substrate, resulting in
poor adhesion of the oxide scale to the substrate.</jats:p>
