Abstract
The composition, microstructures and properties of the Ti(CN) based cermets have been
characterized by using SEM/BSE and energy spectrometer. Results shows that the carbon content of the
cermets through N2 and Ar sintering was lower by 0.5% than vacuum sintering and the nitrogen content of
the cermets through N2 sintering was higher by 20~25% than the Ar and vacuum atmosphere sintering.
When sintered in Ar or N2, the balance between the carbon and nitrogen in the cermets was broken to form
a surface defects, which would result in poor properties. The structure of vacuum sintering is more
uniform and the properties are better.
