摘要： Provided is a coated-surface sliding part having excellent adhesion of a hard coating, and a method for producing the same part. The coated-surface sliding part is a sliding part wherein a hard coating is formed by physical deposition on the surface of a base material formed from, by mass percent, C 0.5 to 0.8%, Si 0.1 to 1.5%, Mn 0.2 to 1.0%, Cr 8.0 to 13.5%, Mo and/or W 0.5 to 4.0% in terms of (Mo+ 1/2 W), and N 0.01 to 0.1%, with the remainder being Fe and impurities. The physically deposited coating is a titanium metal coating further covered by a diamond-like carbon coating. The method for producing a coated-surface part involves sputtering in order to apply the physically deposited coating, which consists of the titanium metal coating and then the diamond-like carbon coating which forms the surface layer, to the surface of the base material having the aforementioned composition. The base material is preferably subjected to argon gas bombardment prior to application of the physically deposited coating.

摘要： A maraging steel for metallic belts which has a composition capable of being reduced in the content of TiN serving as a starting point for fatigue fracture in a high-cycle-rate region. The composition facilitates nitriding to heighten the surface hardness. The steel has a nitrided surface layer having increased compressive residual stress and hence improved flexural fatigue strength. In the steel, former austenite crystal grains have been reduced in size in order to secure higher strength and higher ductility. The maraging steel consists of, by mass %, up to 0.01% C, up to 0.1% Si, up to 0.1% Mn, up to 0.01% P, up to 0.005% S, 17.0-22.0% Ni, 0.1-4.0% Cr, 3.0-7.0% Mo, from more than 7.0 to 20.0% Co, up to 0.1% Ti, up to 2.5% Al, up to 0.03% N, up to 0.005% 0, up to 0.01% B (exclusive zero), and the balance of Fe and unavoidable impurities, wherein Co/3+Mo+4Al is 8.0-15.0%.
摘要翻译：一种用于金属带的马氏体时效钢，具有能够在高循环率区域中作为疲劳断裂起点的TiN含量降低的组成。该组合物有助于氮化以提高表面硬度。钢具有具有增加的压缩残余应力并因此改善的弯曲疲劳强度的氮化表面层。在钢中，为了确保更高的强度和更高的延展性，原奥氏体晶粒尺寸已经减小。马氏体时效钢以质量％计，高达0.01％的C，高达0.1％的Si，至多0.1％的Mn，至多0.01％的P，至多0.005％的S，17.0-22.0％的Ni，0.1-4.0％ Cr，3.0-7.0％Mo，7.0〜20.0％Co，0.1％Ti以下，Al：2.5％以下，N：0.03％以下，B：0以下，不超过0.01％，余量为Fe和不可避免的杂质，其中Co / 3 + Mo + 4Al为8.0〜15.0％。
