高温高圧水中におけるDLC膜の摩耗特性の解明

抄録

Machinery that operates in high-temperature high-pressure water, such as cogeneration engine or heat pump, has a problem of severe wear on its sliding parts. To suppress the wear, a kind of carbon film material called DLC has been drawing attention as a solution because of its wear resistance and low friction coefficient. The focus of this research is to clarify the oxidative wear properties of various DLC films, which enables us to design the optimum DLC for high-temperature and high-pressure water environment.
