ABSTRACT:
The water lubricity of ceramic materials is improved by a method including causing friction of the ceramic materials in the presence of water, thereby forming silanol groups on surfaces undergoing the friction, supplying the surfaces with a water-soluble silane coupling agent having alkoxyl groups to hydrolyze the alkoxyl groups into silanol groups, and reacting the silanol groups formed by the hydrolyzation of the alkoxyl groups with the silanol groups formed on the surfaces, thereby forming a siloxane film having siloxane bonds on the surfaces.
