    • Water-soluble high molecular weight molecules are made present as a dispersing agent in a dispersion coating bath of a solution of a water-soluble nickel salt containing graphite dispersed therein, and a mold for molding glass is immersed therein in a manner that the mold serves as the cathode and the nickel metal serves as the anode in order to effect the electroplating while suppressing nickel or a nickel-based alloy in the film from granular growth in a vertical direction or in the direction of the plane thereof. On the inner surfaces of the mold is formed a film which comprises a matrix of nickel or the nickel-based alloy which as a whole has a flake-like form that is continuous and exists in an open cellular form and a graphite granule phase which is held in the open cells and is outwardly exposed on the surface. Since nickel is suppressed from growing like granules, the film exhibits excellent lubricating property, heat resistance, parting property, abrasion resistance and durability in combination, and is free from defects inherent in the prior art.
    • 水溶性高分子量分子作为分散剂存在于分散在其中的含有石墨的水溶性镍盐溶液的分散涂层浴中,并且将模具玻璃的模具以模具的形式浸入其中 由于阴极和镍金属用作阳极,以便在垂直方向或其平面方向上粒状生长的同时抑制膜中的镍或镍基合金进行电镀。 在模具的内表面上形成薄膜,该薄膜包括镍或镍基合金的基体,其整体上具有连续的薄片状形式,以开孔形式存在,石墨颗粒相为 保持在开放的细胞中并且在表面上向外暴露。 由于镍被抑制成颗粒状生长,因此该膜显示出优异的润滑性,耐热性,分离性,耐磨性和耐久性组合,并且没有现有技术中固有的缺陷。

    • Pitch-based graphitized short fibers formed from mesophase pitch as a raw material, having an average fiber diameter of 5 to 20 μm, a percentage (CV value) of a variance of a fiber diameter with respect to the average fiber diameter of 8 to 15%, a number average fiber length of 20 to 500 μm, and a crystallite size (La) derived from a growth direction of a hexagonal net plane of 30 nm or more, having graphene sheets that are closed upon observation of an end surface of a filler with a transmission electron microscope, and a substantially flat surface observed with a scanning electron microscope, and having an R value, which is a relative intensity ratio (ID/IG) of an intensity (ID) of a Raman band in the vicinity of 1,360 cm−1 to an intensity (IG) of a Raman band in the vicinity of 1,580 cm−1 measured by laser Raman spectroscopy, in a range of 0.01 to 0.07. The short fibers can be filled in a rubber composition at a high density without inhibition of curing of the rubber composition.
