    • PROBLEM TO BE SOLVED: To provide a method for removal of a hard coating film in a superhard material, which can selectively remove the hard coating film provided on the surface of the superhard material such as superhard tools or dice and can minimize the deterioration of a superhard base material.SOLUTION: The superhard base material is produced by sintering superhard alloy particles each comprising a carbide of at least one element selected from the group consisting of group 4, 5 and 6 elements with a binder metal comprising at least one element selected from the group consisting of Fe, Co, Cu and Ni or an alloy containing those elements. The superhard material is produced by coating the superhard base material with a hard coating film containing a nitride, carbide, carbonitride, oxide or boride of at least one element selected from the group consisting of group 4, 5, 6, 13 and 14 elements (excluding carbon). The method for removal of the hard coating film includes bringing the superhard material into contact with an alkaline solution in a treatment container for removing the hard coating film. The film is removed by disposing the superhard base material together with a metal acting on the superhard base material as a sacrificial anode in the alkaline solution in a state of contacting the metal with the superhard base material.
    • 要解决的问题:提供一种去除超硬材料中的硬涂层的方法,该超硬材料可以选择性地去除设置在超硬材料的表面上的硬涂层,例如超硬工具或骰子,并且可以最小化 超硬基材的变质。 解决方案:超硬母材是通过烧结超硬合金粒子制成的,所述超硬合金粒子包含选自组4,5,6的元素中的至少一种元素的碳化物,所述粘合剂金属包含至少一种选自 由Fe,Co,Cu和Ni组成的组或含有这些元素的合金。 通过用含有选自组4,5,6,13和14元素中的至少一种元素的氮化物,碳化物,碳氮化物,氧化物或硼化物的硬涂层涂覆超硬基材来制造超硬材料( 不含碳)。 去除硬涂膜的方法包括使超硬材料与用于除去硬涂膜的处理容器中的碱溶液接触。 通过在与金属与超硬基材接触的状态下,将超硬基材与作为牺牲阳极的金属作为牺牲阳极一起配置在超硬母材上与碱金属溶液中配置。 版权所有(C)2013,JPO&INPIT

    • PURPOSE:To clean and activate a surface to be electroless-plated and to form an electroless plating film excellent in adhesiveness by treating the acid-treated surface with a pretreating soln. contg. an alkali cyanide, reducing agent, its stabilizer, pH regulator and surfactant. CONSTITUTION:When the surface of a nonconductive material is electroless- plated with Ni, etc., the surface to be plated is treated with acid, cleaned and activated, the smut generated in the acid treatment is removed, and the material is electroless-plated. An aq. soln. contg. an alkali cyanide, a hypophosphite, a borohydride, etc., as the smut reducing agent, an aliphatic carboxylic acid, a Tl compd., etc., as the reducing agent stabilizer, phosphoric acid and citric acid or their salts, polyethylene glycol, etc., as the surfactant, etc., is used as the smut removing pretreating soln. Since the oxides such as smut are removed and the substrate is etched with the alkali cyanide, the surface to be treated is sufficiently activated, and a uniform electroless-plating layer excellent in adhesiveness is formed.
