Lubricating film and method of manufacturing the same.

摘要

A chemically adsorbed film comprising carbon-chain organic molecules is formed on a substrate surface via covalent bonds, and organic compounds comprising carbon chains are physically adsorbed to the surface of the chemically adsorbed film, thus providing a lubricating film which is thin and durable against friction, and with good anti-abrasion and sliding properties. The thickness of the lubricating film is at the nanometer level. More specifically, a lubricating film is made by forming a chemically adsorbed film on a substrate surface after dipping and holding the substrate in a nonaqueous solution dissolving chemical admolecules, and by coating a chloroform solution of a long-chain hydrocarbon-based fatty acid ester compound on the surface of the chemically adsorbed film.
