چکیده انگلیسی
The presented study defines the impact of aluminizing process by out-of-pack method on the oxidation resistance of cast Ti-47Al-2W-0.5Si alloy after homogenising and hot isostatic pressing. The surface condition was characterized, as well as chemical and phase composition of scale formed on examined alloy with and without protective coating, when subjected to cyclic oxidation at 950 °C. It was established that the generated hermetic and compact aluminium diffusion coating with a thickness of about 7.5 μm, consisting mainly of TiAl2 phase, has a significant effect on the improvement of cyclic oxidation resistance in the case of investigated alloy. It was confirmed that the scale formed after the oxidation process on the surface of alloy with protective coating was composed mainly of Al2O3 oxide, contrary to the scale formed on the alloy without protective coating, which was mainly consisting of TiO2 oxide.
