“…7) [38]. Inoue et al recently reported the plasma nitridation of TiAl to form Ti 2 AlN, and by quantum chemical simulation found evidence that formation of the ternary nitride was influenced primarily by chemical interaction of the N with the Ti sublattice [39,40]. The formation of Ti 2 AlC was also reported by plasma carburization of TiAl [41], although oxidation resistance of the carburized surface was apparently not studied.…”

This paper discusses strategies for controlling the surface chemistry and microstructure of materials to form protective and functional surfaces through controlled gas-metal reactions. Potential applications range from oxidation, corrosion, and wear resistance to electrochemical devices such as fuel cells to catalysts. Phenomenological examples are presented for coatings designed to self-grade under oxidizing conditions, and for the growth of simple and complex (binary and ternary) nitride and carbide phase surface layers by nitridation and carburization reactions. Specific systems discussed include environmental barrier coatings (EBCs) for Si-based ceramics such as Si 3 N 4 and SiC, the growth of continuous, protective CrN/Cr 2 N, TiN, VN, NiNbVN, and related simple nitride layers on Fe-and Ni-base alloys, the possible formation of ternary nitride and carbide surface phases (e.g. Ti 3 AlC 2 and related MAX-phases) on intermetallic surfaces to improve oxidation resistance, and the formation of composite near-surface structures in Ag-SiO 2 and Co(Mo)-Co 6 Mo 6 C 2 systems.
