| 20100151263 | METALLIC SURFACE ENHANCEMENT - A method and composition for enhancing corrosion resistance, wear resistance, and contact resistance of a device comprising a copper or copper alloy substrate and at least one metal-based layer on a surface of the substrate. The composition comprises a phosphorus oxide compound selected from the group consisting of a phosphonic acid, a phosphonate salt, a phosphonate ester, a phosphoric acid, a phosphate salt, a phosphate ester, and mixtures thereof; an organic compound comprising a nitrogen-containing functional group; and a solvent having a surface tension less than about 50 dynes/cm as measured at 25° C. | 06-17-2010 |
| 20100294669 | ELECTROLYTIC DEPOSITION OF METAL-BASED COMPOSITE COATINGS COMPRISING NANO-PARTICLES - A method is provided for imparting corrosion resistance onto a surface of a substrate. The method comprises contacting the surface of the substrate with an electrolytic plating solution comprising (a) a source of deposition metal ions of a deposition metal selected from the group consisting of zinc, palladium, silver, nickel, copper, gold, platinum, rhodium, ruthenium, chrome, and alloys thereof, (b) a pre-mixed dispersion of non-metallic nano-particles, wherein the non-metallic particles have a pre-mix coating of surfactant molecules thereon; and applying an external source of electrons to the electrolytic plating solution to thereby electrolytically deposit a metal-based composite coating comprising the deposition metal and non-metallic nano-particles onto the surface. | 11-25-2010 |
