    • PROBLEM TO BE SOLVED: To provide an exhaust gas control device achieving miniaturization, weight saving or energy saving, in comparison with the past.SOLUTION: This exhaust gas control device (3) includes: a control valve (24) disposed in the exhaust gas path of an internal combustion engine and controlling an exhaust gas flow; a movable shaft (27) moving integrally with the control valve; and bearings (34, 39) supporting the movable shaft while sliding the movable shaft and having a slide receiving surface made to slidably contact the sliding surface of the movable shaft. At least one of the sliding surface and slide receiving surface has an amorphous carbon film (DLC-Si film) consisting of Si, H and C as a balance, and the DLC-Si film is composed of a critical part facing an adhering interface and a surface part connected to the critical part and extending to the side of a surface. The surface part has a portion where an Si concentration is 8-30 atom%, and the critical part has the Si concentration lower than that in the surface part. Since the DLC-Si film exists in a sliding part, a coefficient of friction in an ordinary temperature region and a high-temperature region is reduced over a long period of time.
    • 要解决的问题:与过去相比,提供实现小型化,减轻重量或节能的废气控制装置。解决方案:该排气控制装置(3)包括:设置在废气中的控制阀(24) 内燃机的路径并控制废气流; 与所述控制阀一体移动的可动轴(27); 以及支承可动轴的轴承(34,39),同时滑动可动轴并具有滑动接触表面,滑动接触表面可移动轴。 滑动表面和滑动接收表面中的至少一个具有由Si,H和C组成的非晶碳膜(DLC-Si膜),并且DLC-Si膜由面向粘合界面的临界部分组成, 连接到临界部分并延伸到表面侧面的表面部分。 表面部分具有Si浓度为8-30原子%的部分,临界部分的Si浓度低于表面部分。 由于DLC-Si膜存在于滑动部分中,因此在常温区域和高温区域中的摩擦系数长时间地减少。

    • PROBLEM TO BE SOLVED: To provide an amorphous carbon coating film member combining excellent wear resistance and low counterpart aggressiveness.SOLUTION: An amorphous carbon coating film consists of a conductive substrate and an amorphous carbon coating film fixed to at least a part of the surface of the substrate, the amorphous carbon coating film is based on carbon and is a gradient composition coating film containing silicon whose concentration is continuously gradient in such a manner that the concentration silicon is highest on the substrate side and hydrogen whose concentration is continuously gradient in such a manner that the concentration of hydrogen is lowest on the substrate side. Since the amorphous carbon coating film is a gradient composition coating film containing silicon whose concentration is continuously gradient in such a manner that the concentration of silicon is highest on the substrate side, the substrate side has high hardness, securing strength of the amorphous carbon coating film. In addition, since the amorphous carbon coating film is a gradient composition coating film containing hydrogen whose concentration is continuously gradient in such a manner that the concentration of hydrogen is lowest on the substrate side, the hardness of the amorphous carbon coating film is low on the front surface side, resulting in reduction of counterpart aggressiveness.
    • 要解决的问题:提供一种具有优异的耐磨性和低对应物侵蚀性的无定形碳涂膜构件。解决方案:无定形碳涂膜由导电基材和固定在表面的至少一部分的无定形碳涂层 基体,无定形碳涂膜基于碳,是含有浓度连续梯度的硅的梯度组合物涂膜,其浓度硅在基板侧最高,浓度为浓度连续梯度的氢 氢的浓度在衬底侧最低的方式。 由于无定形碳涂膜是含有浓度连续梯度的硅的梯度组合物涂膜,因此在基板侧硅的浓度最高,基板侧具有高硬度,确保无定形碳涂膜的强度 。 此外,由于无定形碳涂膜是含有氢的梯度组合物涂膜,其浓度以基板侧的氢浓度最低的浓度连续梯度,因此无定形碳涂膜的硬度低 前表面侧,导致对应的侵蚀性降低。

    • PROBLEM TO BE SOLVED: To provide a new coated cemented carbide member which is obtained by covering the surface of a cemented carbide with an amorphous carbon film, and has adhesion improved by forming the surface of the base material into a specified rugged face.
      SOLUTION: The coated cemented carbide member includes: the base material 10 made of a cemented carbide composed of a hard phase 12 containing tungsten carbide and a binder phase 11 containing iron group metal; and the amorphous carbon film 2 covered on the surface of the base material 10. The surface of the base material 10 covered with the amorphous carbon film 2 is a rugged face 10f having a recessed part 12
      - from which the hard phase 12 is lost, and when the average particle diameter of WC is defined as X[μm], the maximum depth of the recessed part as Y[μm] and the area ratio of the binder phase in the rugged face as Z[%], by controlling the values of X, Y and Z to prescribed ranges, an anchor effect improves the adhesion between the surface of the base material 10 and the amorphous carbon film 2.
