Abstract:
A method of forming films over an inner surface of a cylindrical member having a bore, said method comprising:an intermediate film forming process comprising steps of:placing the cylindrical member in a vacuum vessel,inserting an electrode of an intermediate film forming material for enhancing adhesion of a hard carbon film in the bore of the cylindrical member, and keeping the cylindrical member at a ground potential or a floating potential, andapplying an AC voltage to the electrode after evacuating the vacuum vessel to form an intermediate film over the inner surface of the cylindrical member by resistance heating evaporation of the electrode; anda hard carbon film forming process comprising steps of:placing the cylindrical member having the intermediate film formed over the inner surface thereof in a vacuum vessel,inserting an electrode in the bore and keeping the electrode at a ground potential,supplying a gas containing carbon into the vacuum vessel after evacuating the same, andapplying a voltage to the cylindrical member to produce a plasma in the vacuum vessel in order that the hard carbon film is deposited on the intermediate film formed over the inner surface of the cylindrical member.
