Notes:
In this study, plasma niobium alloying of the TiAl based alloys has been carried out at1050, 1100 and 1150°C. The effect of the alloying temperature on the characteristic of the alloyedlayer was investigated by optical microscopy, scanning electronic microscopy (SEM), glow dischargespectrum (GDS) and energy dispersive spectrum (EDS). The results show that the surfaceroughness, chemical composition and thickness of the alloyed layer increased with the alloyingtemperature which is dependent on the sheath potential. A deposition layer formed on the TiAl surfaceat 1150 °C was resulted from the larger sheath potential or the stronger sputtering of sourceelectrode
