Guide bush and method of forming diamond-like carbon film over the guide bush

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（中）：

本发明提供了一种引导衬套，其中至少含有钴的硬质合金合金设置在其内表面上，用于将切削工具在其纵向轴向方向上可旋转地且可滑动地保持在工件上，并且DLC膜形成在硬质合金合金，钴从硬质合金表面除去，与DLC膜相邻。通过在去除了钴的硬质合金12的表面上形成DLC膜15，在其间形成有中间层，DLC膜与固定在引导衬套的内表面上的硬质合金的粘合性是进一步增强。
