T1 - A study on tribological behaviour of a-C:H coatings under lubricated conditions up to 250°C T2 - Proceedings of the 6th International Conference on Mechanics and Materials in Design N2 - The influence of temperature and counterbody material on the tribological properties of a-C:H coatings deposited on Cronidur 30 steel has been investigated in a lubricated ball on disk contact situation with alpha-alumina and silicon nitride as counterbodies. The results show, that the wear volumes of the systems increase exponentially with increasing temperature, for alpha-alumina more than for silicon nitride. Two different wear mechanisms seem to have a major influence: First, the abrasive action due to materials hardness and second, the tribo-oxidation when silicon nitride is counter material.
