摘要:
The present invention provides a plated article that has a thin seed layer having uniform thickness, formed by electroless plating and allowing formation of ultrafine wiring, and that avoids the complicated formation of a bilayer of a barrier layer and a catalytic metal layer prior to forming the seed layer. The present invention also provides a method for manufacturing the plated article. The plated article has an alloy thin film formed on a substrate and having a catalytically active metal (A) for electroless plating and a metal (B) capable of undergoing displacement plating with a metal ion contained in an electroless plating solution, and a metal thin film formed on the alloy thin film by electroless displacement and reduction plating. The alloy thin film of the catalytically active metal (A) and the metal (B) capable of displacement plating has a composition comprising 5at% to 40at% of the metal (A). The metal thin film formed by electroless displacement and reduction plating is a metal thin film having a thickness no greater than 10 nm and a resistivity no greater than 10 µΩ·cm. Preferably, the metal (B) has a barrier function with respect to a metal of the metal thin film.

An exemplary method of making a first component for contacting another component includes applying a wear and corrosion resistant material layer onto a surface of the first component. The wear and corrosion resistant material layer is then roughened subsequent to having been applied to the surface. A component comprises an exemplary elevator sheave that includes a metallic body having a sheave surface that is adapted to contact an elevator tension member. A corrosion resistant material layer on the sheave surface has a thickness that is greater than about 5 microns.

An electrical device having PTC conductive polymer is made by combining electrodes, in which electroless nickel plating is formed on an electrolytic copper foil, with PTC conductive polymer. The electrodes have electroless-plated nickel layers at both sides of an electrolytic copper foil and the PTC conductive polymer is welded between the electrodes in a sandwich type.Because the electroless-plated nickel of the electrical device has even thickness, the electrical device gives improved PTC characteristics and good chemical and mechanical binding capacity between the electrodes and the PTC conductive polymer.

The invention is directed to a nodular nickel boron coating having lubricating properties. Nodular and columnar boron coatings made by the above methods disclosed in the above patents have a low coefficient of friction. The above process results in a columnar structure with nodules in the surface layer. Nodules can be produced in other nickel coatings by blasting the surface with hard particles to form the nodules. Using blasting to form the nodules produces an inferior coating in contrast to the electroless nickel boron coatings having a columnar structure.
