  • Publication number: 20130264215
    Abstract: The present invention relates to an anode system for conventional electrolysis cells, a process for the production thereof and its use for the deposition of electrolytic coatings. The anode system is characterized in that the anode (2) is in direct contact with a membrane (3) which completely separates the anode space from the cathode space. This anode system is therefore a direct-contact membrane anode.

  • Publication number: 20090223830
    Abstract: A surface treatment method of cladding a Sn or Sn alloy coating with one or more metals selected from among Mn, Fe, Ru, Os, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Ga, In, Ti, Ge, Pb, Sb and Bi continuously or discontinuously in such a way as to make the Sn or Sn alloy coating partially exposed, which method makes it possible to inhibit the generation of whiskers in an Sn or Sn alloy coating formed on the surface of a substrate to which other member is pressure-welded or the joint surface to be soldered. Cladding an Sn or Sn alloy coating with a prescribed metal continuously or discontinuously in such a way as to make the coating partially exposed inhibits the generation of whiskers by contact pressure in pressure welding, and further inhibits the generation of whiskers without impairing the solder wettability of the coating even when the cladding is not followed by heat treatment or reflowing.

  • Patent number: 6911068
    Abstract: A metal plating bath containing organic compounds that inhibit or retard the consumption of plating bath additives. The additives are chemical compounds that improve the brightness of the plated metal, the physical properties of the plated metal especially with respect to ductility and the micro-throwing power as well as the macro-throwing power of the plating bath. The organic compounds that inhibit or retard the consumption of additives increases the life of the plating bath and improves the efficiency of the plating process. The plating baths containing the organic compounds that inhibit or retard additive consumption can be employed to copper, gold, silver, palladium, platinum, cobalt, cadmium, chromium, bismuth, indium, rhodium, ruthenium, and iridium.

  • Patent number: 6852210
    Abstract: To provide a plating method, which enables wide industrial use of the redox system electroless plating method having excellent characteristics, and a plating bath precursor which is preferable for the plating method. The plating method comprises a process oxidizing first metal ions of a redox system of a plating bath from a lower oxidation state to a high oxidation state, and second metal ions of said redox system are reduced and deposited onto the surface of an object to be plated, wherein a process is provided in which by supplying the electrical current to the plating bath, the first metal ions are reduced from said lower oxidation state to thereby activate the plating bath. The plating bath precursor is formed stabilizing the plating bath so that reduction and deposition of the second metal ions substantially do not occur in order to improve its storing performance.

  • Publication number: 20040163966
    Abstract: A copper welding rod is used in an arc-welding operation to form a bead that joins a copper starter sheet and a stainless steel hanger bar. The amperage level of the arc-welding equipment is set to generate heat at the weld site which is above the melting point of copper and below the melting point of stainless steel. This results in a welded joint between the copper bead and the hanger bar and a brazed joint between the copper bead and the starter sheet. Since brazing produces little or no fusion, the area of contact between the two dissimilar metals is limited to the interface between them, which significantly reduces the damaging effects of galvanic corrosion. Another improvement lies in the application of a corrosion-resistant metallic coating on the joint between the hanger bar and the starter sheet using a high velocity oxygen fuel flame spray technique.
