    摘要: Thin-walled bearings (10) each including a layer (16) of an aluminium based, or copper based, bearing material bonded to a steel shell, has an overlay (20) of one or more of the elements lead, tin, indium, copper, nickel, zinc and antimony. A flash (24) less than two micrometres thick and of one or more of the elements iron, chromium, nickel, cobalt, gold, silver and copper, is provided in any convenient way on the initially unmodified exposed surface portion of the overlay. The flash (24) is caused to react with the, or at least one constituent, element of the overlay (20) to modify the surface portion (22) of the overlay to become hard and wear-resistant. The material of the flash (24) forms at least one intermetallic compound, and/or solid solution, with the material of the surface portion (22) of the overlay (20). The bearing may be heated to a temperature at which the flash (24) reacts with the overlay (20) to form the required intermetallic compound, and/or solid solution, at a desired rate.

    摘要: A clad material (10) is constructed such that a metallic lath sheet (3) is laminated on a base metal layer (1), a covering metal layer (4) is laminated on the metallic lath sheet (3) on a side opposite to the base metal layer (1), and these base metal layer (1), metallic lath sheet (3) and the covering metal layer (4) are integrally bonded together. The metallic lath sheet (3) is used, in which a metallic sheet having a plurality of cuts formed throughout in a zigzag manner and extending therethrough in a direction of sheet thickness is deformed in a direction crossing the direction of formation of the cuts and meshes are formed by opening the cuts in the direction of deformation.

    摘要: The present invention, which is aimed at providing a method for manufacturing a clad material that can be used for the anode cases and cathode cases of button-type microbatteries and other miniature electronic devices requiring the use of comparatively thin, drawable sheets, allows the difference between r values, or Lankford values (which characterize the plastic anisotropy between the rolling/bonding direction of a clad material and a direction at a prescribed angle to the rolling/bonding direction) to be reduced by performing cold rolling at a rolling reduction of 30% or lower in addition to performing a conventional method for manufacturing a clad material, making it possible to substantially enhance the mechanical strength of the clad material and to mass-produce clad materials that have low reduction anisotropy.

    摘要: A technique for producing soldering iron tips entails cutting clad wire into a plurality of segments, each segment comprising a core of material (such as copper) and an outer protective layer (such as stainless steel, Ni, Cr, or alloy thereof). Each clad wire segment is then shaped into a soldering iron tip by a cold or hot heading process, or other metal forming process. In the finished tip, the protective outer layer is disposed behind the working area of the tip, and serves to reduce the corrosion of the tip, and to improve the electrical conductivity between the tip and the soldering iron handle. A heater element can be formed at one end of the soldering iron tip from the same clad wire segment used to produce the tip itself, thereby ensuring good thermal transfer properties between the heater element and the tip. The invention also pertains to a technique for forming a protective outer layer on the working area of the tip. The technique comprises stamping caps from a thin strip or sheet of protective material, such as iron. More specifically, the caps are stamped out of the sheet using a die having a shape which resembles the shape of the working area of the soldering tip. The caps formed in this manner are then inserted over the ends of the tips, and attached thereto by applying brazing material to the formed cap or to the strip of material prior to forming the cap.

    摘要翻译: 用于生产烙铁头的技术需要将包覆线切割成多个节段,每个节段包括材料(例如铜)的芯和外部保护层(例如不锈钢,Ni,Cr或其合金)。 然后通过冷或热镦锻工艺或其他金属成形工艺将每个包层线段成形为烙铁头。 在完成的尖端中,保护性外层设置在尖端的工作区域后面,并且用于减少尖端的腐蚀并且改善尖端和烙铁手柄之间的导电性。 加热器元件可以形成在烙铁头的一端与用于产生烙铁头本身的同一包层线段相连,由此确保加热器元件和烙铁头之间良好的传热性能。 本发明还涉及在尖端的工作区域上形成保护性外层的技术。 该技术包括从薄片或片材如铁等保护材料上冲压盖帽。 更具体地说,使用具有与焊接头的工作区域的形状类似的形状的模具,将盖帽从薄片上冲压出来。 然后将以这种方式形成的盖帽插入尖端的端部上,并且在形成盖帽之前通过将钎焊材料施加到成形的盖或材料条上而将其连接到其上。
