Synthesis of Al₂O₃/Ti/TiN Functional Graded Materials by Means of Nitriding in Salts of Al₂O₃/Ti Composites

Abstract:

The synthesis of Al₂O₃/Ti/TiN functional graded material (FGM) through the nitriding in salts of previously Al₂O₃-10 vol. % Ti fabricated composites was studied. The matrix for the preparation of the FGM is formulated of an Al₂O₃-based composite that presents a homogeneous dispersion of very fine metallic titanium particles. After nitriding process, microstructural observations were carry out on the transversal zone of the materials’ surface showing the presence of a very thin film of about 37 µm of a constituent that was identified as TiN. Micro-hardness measurements performed from the surface to the core of the FGM confirm an increment on the hardness near the material’s surface.
