Gas phase aluminizing of TiAl intermetallics

The aim of this study was the microstructural characterization of aluminide diffusion coatings deposited on Ti48Al2Cr2Nb and Ti46Al7Nb alloys. The coatingsʹ deposition process was prepared using out of pack method. The X-ray diffraction phase analysis from the surface of coatings indicated that TiAl2 phase dominates in the coating. The thickness of aluminide coating was about 10 μm.
