Abstract:
Dense Al2O3-TiN composites with 5-25 vol% TiN were manufactured by thehot pressing technique. The effect of the content of a dispersion-toughening
aid, TiN, on the mechanical properties, electrical resistivity, oxidation
resistance and wear resistance were studied and related to the
microstructure. The ceramic with a content of 25 vol.% TiN was characterized
by the highest strength, 567 MPa, the lowest electrical resistivity, 2.5x103
Omega.cm, and was suitable for electrical discharge machining. 8 refs.
