High temperature oxidation resistance of (Ti,Ta)(C,N)-based cermets [PDF]
, 2016 Cermets based on titanium–tantalum carbonitride were oxidized in static air between 800 °C and 1100 °C for 48 h. The thermogravimetric and microstructural study showed an outstanding reduction in the oxidation of more than 90% when the Ta content was ...
