    摘要： The invention provides a guide bush wherein a cemented carbide alloy containing at least cobalt is provided on an inner surface thereof for holding a workpiece rotatably and slidably in the longitudinal axial direction thereof in close proximity of a cutting tool, and a DLC film is formed over the cemented carbide alloy, cobalt being removed from the surface of the cemented carbide alloy, adjoining the DLC film. By forming the DLC film 15 on the surface of the cemented carbide alloy 12 from which cobalt has been removed, with an intermediate layer formed therebetween, adhesiveness of the DLC film against the cemented carbide alloy fixedly attached to the inner surface of the guide bush is further enhanced.

    摘要： A hard carbon film (15) is formed directly or through an intermediate layer for enhancing adhesion over an inner surface (11b) and over a portion (11h.sub.1) of an end face (11h) of a guide bush 11 adjacent to the end of the inner surface for holding a workpiece (51) rotatably and axially slidable on an automatic lathe at a position near a cutting tool, to be in sliding contact with the workpiece (51) or directly or through an intermediate layer for enhancing adhesion on the surface of a superhard lining fixed to the inner surface (11b) in a plasma CVD process employing an auxiliary electrode and a dummy member. Thereby, the guide bush (11) has remarkably enhanced durability and prevents seizing that makes a machining operation impossible, even when the guide bush (11) is used for an extended period of time and when the automatic lathe operates for heavy machining. Flaws caused by flashes on the workpiece are prevented from occurring on the inner surface of the guide bush (11).

    摘要： A hard carbon film is formed directly or through an intermediate layer for enhancing adhesion over an inner surface of a guide bush in such a manner that the thickness of the inner surface at the portion near an open end is greater than that at the inner portion thereof, wherein the inner surface is in sliding contact with a workpiece and the guide bush is mounted on an automatic lathe for holding the workpiece rotatably and slidably in the axial direction near a cutting tool. Accordingly, the guide bush is disposed in a vacuum vessel to form a hard carbon film of a hydrogenated amorphous carbon over the inner surface of the guide bush by a plasma CVD method. At this time, a rodlike auxiliary electrode provided with a stepped portion having an extremity which is smaller than another portion or a rodlike auxiliary electrode provided with a tapered portion having an extremity is inserted into the center bore forming the inner surface of the guide bush in such a manner that the extremity of the tapered portion is positioned near the open end of the inner surface of the guide bush, and the auxiliary electrode is grounded or a positive DC current is applied to the auxiliary electrode.
