Because of the oxidation resistance of γ-TiAl-alloys the long term use is limited to temperatures up to 700 C. In literature, it has been reported that the so called halogen effect has an outstanding improvement on the oxidation resistance of γ-TiAl. This implication is based on the forming of gaseous Al-halides which are oxidized to Al2O3 on the surface resulting in a protective alumina scale.To investigate the absorption of fluorine in γ-TiAl during electroslag remelting and to enhance the oxidation resistance of the produced alloy by bulk-fluidization a series of tests was performed at IME. Hence, in a 400 kW lab scale furnace multiple electrodes of Ti-45Al were remelted by using a CaF2 flux. The slag composition was varied by partially substitution of CaF2 with MgF2. The alloys as well as the slag were analyzed on their composition to set up the fluorine content by influencing the melting parameters.
