This compound as well as similar compounds(such as TiN and TiCN) are most notably used for coating machine tools such and endmills and drills to change their properties, such as increased thermal stability and/or wear resistance. Four important compositions (metal content 100 wt.%) are deposited in industrial scale by physical vapor deposition methods:
