High temperature oxidation of Ti-48Al-8Cr-2Ag alloy with sputtered coating at 1000°C in air
Source abstract
Abstract
Magnetron-sputter deposition was used to produce a Ti-48Al-8Cr-2Ag (at.%) coating on a cast alloy substrate with the same composition. The oxidation behaviour of the cast Ti-48Al-8Cr-2Ag alloy and its sputtered coating was investigated in air at 1000°C. The resulting scale structures were analyzed in great detail by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The nanocrystalline coating showed higher oxidation rate than the cast alloy, because an outer TiO2 layer formed over a finegrain Al2O3 scale on the coating. The oxidation mechanism was discussed.
