Popis: By increasing the addition of Si and N to diamond-like carbon (DLC), the amorphous ceramic silicon-carbonitride (SiCN) can be obtained. An advantage of SiCN compared to DLC is its high thermal stability, represented by a crystallisation temperature of 1 500 °C and its increased oxidation resistance. To investigate the thermal stability of a-SiCN:H thin films, samples with different carbon contents have been produced by plasma immersion ion implantation and deposition (PIII&D). The films have been annealed at temperatures up to 1 000 °C in O2 as well as Ar. By examining the chemical composition, bonding structure and mechanical properties, a distinct carbon fraction could be determined, which marks the transition from (doped) a-C:H with low thermal stability to a-SiCN:H with high temperature resistance.
