A comparison of composite TiN/a-C films produced from various carbon sources
Abstract
Titanium nitride (TiN)/amorphous carbon (a-C) composite films are deposited on stainless steel with various carbon sources via magnetron sputtering in a magnetized sheet plasma source. The different carbon sources used in the carbonitriding process are graphite target and acetylene and methane gases. It is shown that the carbon source used in producing TiN/a-C composite films affect film properties such as elemental content, surface morphology, TiN phases, and hardness.
