Abstract
The present invention provides a sliding member which is a combination of sliding members to be operated in water-based environments and which has excellent wear resistance in water-based environments. An amorphous carbon film with a thickness of 0.1 to 5 μm and a hardness of 7 to 25 GPa is formed on at least one of the sliding surfaces of the sliding part of the sliding member. In a preferred mode, a hydrogenated amorphous carbon film comprising 5 to 40 at % hydrogen is formed as the aforementioned amorphous carbon film so as to achieve greater wear resistance.
