Kurzfassung
The goal of the paper was to elucidate the effect of a Ti5Si3 interlayer on the high temperature oxidation resistance of the Al-Ti coatings. During cyclic oxidation at 900 °C for 1000 1 h cycles, the coating system with a Ti5Si3 interlayer maintained the Al-rich phases of TiAl3 and TiAl2 in the Al-Ti top layer around 5–10 times longer compared to a coating without intermediate barrier layer. Moreover, the substrate alloying elements (Nb and Cr) are suggested to have a noticeably positive impact on the reduced Al diffusion due to segregations at the grain boundaries in the Ti5Si3 interlayer.
