A Comparative Research on the Compositions and Microstructure of the Ti(CN) Based Cermets in Different Sintering Atmospheres

摘要：

　　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.
