    摘要: A new class of electrically conductive, wear resistant, and high thermal stability nanocrystalline noble metal coatings achieved by codeposition of an insoluble, unreactive, and thermally stable, grain boundary segregated ceramic species that strengthens the base metal by inhibiting grain boundary mobility and recrystallization during deposition. These coatings exhibit high hardness and wear resistance while maintaining electrical conductivity effectively equivalent to that of the pure, fine-grained base metal. The coatings exhibit relatively low friction coefficients in nominally unlubricated sliding, and high thermal stability. The friction, wear, and electrical contact characteristics of these coatings are comparable or superior to electroplated hard gold films used extensively in electrical contact applications. The use of physical vapor deposition techniques such as electron beam evaporation provides an environmentally friendly alternative to electroplating for the synthesis of high performance hard gold films.

    摘要: An improved outer layer of plating comprising a binary metal alloy of gold and palladium is employed on connector contacts. The binary metal alloy is plated on at least the contact surface of the contacts. Intermediate plating layers can be applied between the outer layer of gold and palladium and the conductive base of the contacts. The binary metal alloy of gold and palladium may be configured to have a mostly gold or a mostly silver appearance, depending upon the relative concentration of gold and palladium in the binary metal alloy.

    摘要: High-temperature solders having a higher melting point than solder alloys used for soldering of printed circuit boards are used for internal bonding of electronic parts, but high-temperature solders which are free from Pb have not been developed. There exist high-temperature solders which comprises Sn balls and Cu balls and which perform bonding through the formation of an intermetallic compound without melting to form a single-phase structure, but they have poor wettability to the lands of a printed circuit board or electrodes of electronic parts and have not been used.A solder paste according to the present invention is provided by mixing flux with a powder mixture of Sn powder or an Sn based lead-free solder powder with Cu or Ag powder which has Ni plating formed on its surface. Although the solder paste performs bonding by means of an intermetallic compound without melting to form a single phase structure, the Ni plating acts as a barrier which retards the formation of the intermetallic compound so as to leave enough time to permit wetting of the lands of a printed circuit board or electrodes of an electronic part.

    摘要: This Invention concerns a ring (11) or other accessory and jewelry goods provided with a pattern resulting from processing a metal underlayer (111) of a noble metal and/or a metal plating layer (112) formed on the metal underlayer (111). The noble metal jewelry goods has the metal plating layer (112) formed in a uniform thickness on the whole upper surface of the metal underlayer (111) and has the metal underlayer (111) and/or the metal plating layer (112) enabled by the rod-shaped grinding tool (12) to form glossy regions (111-1) and (111-2) exposing the metal underlayer (111). The noble metal jewelry goods of this invention is enabled to form the metal plating layer region (112) that has not been ground by the rod-shaped grinding tool (12) at all and expose the metal plating layer. The method for the production of the noble metal jewelry goods causes the metal underlayer (111) and/or the metal plating layer (112) of the noble metal jewelry goods to be linearly ground as controlled in fine variation in length, depth and pitch in the direction of the line width and consequently allows formation of different light reflection regions (113) showing no clear periphery of the pattern as compared with the pattern manufactured by using a mask. Thus, the produced noble metal jewelry goods deserves a high price.
