Abstract
The object of the present invention is to provide sliding members having preferable lubrication and seizure resistance. Sliding members comprising a columnar texture which is composed from at least one of metal nitrides, metal oxides, metal carbides, and metals on a base member, wherein the columnar texture is composed of assemblies of fine columnar asperities, with intervals formed between the columnar asperities being connected to each other so as to form a net work, and with gaseous, liquid, or solid lubricants being maintained in the intervals. The mutually connected intervals in the columnar texture are superior in filling and holding of lubricants, and the above described superiorities improve lubrication and seizure resistance and extend sliding life.
