초록
The production of Al2O3/Ti/TiN functional materials through the nitriding in ammonia salts of previously Al2O3/Ti fabricated composites was achieved. The matrix for the preparation of the functional materials is to create an Al2O3-based composite that presents a fine and homogeneous dispersions of very fine metallic particles of Ti. After the nitriding, microstructural observations were carried out on the transverse zone of the materials’ surface showing the presence of a very thin film of about 20 μm of a constituent that was identified with the help of EDS as TiN. In addition, measurements of micro-hardness on the surface and in the core of the functional material were realized in order to determine the effect of nitride formation on the hardness.
