    • @ A method in which a granular abrasive, together with a deposited metal, is deposited on a base metal for an electro-deposition on a tool by electroplating. A cathode chamber (4) is provided in an electrolytic tank (1) in such a manner that a portion of the cathode chamber (4) projects beyond the anolyte surface Sa. A granular abrasive layer (8) is formed on the bottom of the cathode chamber (4). A portion of an anolyte in an anode chamber (7) is circularly poured into the cathode chamber (4) from the upper side thereof such that a head difference (Sc-Sa) is formed between the catholyte surface Sc and the anolyte surface Sa, whereby such plating conditions as the pH of the catholyte and the metal concentration are controlled such that the granular abrasive (8) is deposited on a base metal (3) without diffusing the granular abrasive layer (8). The method is suitably employed to manufacture an electrodeposition plated tool in such a manner that a granular abrasive, such as diamond, cubic boron nitride or fine ceramic is deposited on a base metal for various grinding, polishing or cutting tools, together with a metal, such as nickel or copper.
    • 将粒状研磨剂与沉积的金属一起沉积在基底金属上以通过电镀在工具上进行电解的方法。 阴极室(4)以使阴极室(4)的一部分伸出阳极电解液表面Sa.的方式设置在电解槽(1)中。 在阴极室(4)的底部形成粒状研磨层(8)。 阳极室(7)中的阳极电解液的一部分从其上侧循环地注入阴极室(4),使得在阴极电解液表面Sc和阳极电解液表面Sa之间形成头部差异(Sc-Sa) 由此控制如阴极电解液的pH值和金属浓度这样的电镀条件,使得粒状磨料(8)沉积在基体金属(3)上,而不会使粒状磨料层(8)扩散。 该方法适用于制造电沉积电镀工具,使得诸如金刚石,立方氮化硼或精细陶瓷的颗粒磨料与金属一起沉积在用于各种研磨,抛光或切割工具的母材上, 例如镍或铜。
