摘　　要：Boriding of the Ti-Al intermetallic GE48-2-2 at 1273 K for 10 hours was performed. In order to ensure that no any serious alteration occurred in the substrate, it was previously examined with X-Ray Diffractometry (XRD), after it has undergone an annealing process at the temperature of boronizing. Subsequently, we examined the coating with XRD and Scanning Electron Microscopy, in order to characterize its structure and morphology. A dense TiΒ2 layer, 10 - 15 μm thick, was formed, but also Cr2B3 and NbN, BN and some Ti-Al phases were detected. Efforts were undertaken to focus on influence of the substrate modification, towards the quality of the coating.Boriding of the Ti-Al intermetallic GE48-2-2 at 1273 K for 10 hours was performed.
