摘要:
A substrate for a printed wiring board, comprising an insulating base and a conductive layer covering a surface of the base, wherein the base has a through-hole penetrating the base, and the conductive layer is composed of a conductive ink layer that covers the entire inner surface of the through-hole and an upper surface and a lower surface of the base and that contains metal particles.

A decorative article having a while film, comprising a white-tone stainless steel film formed on at least part of a surface of a metallic or non-metallic base material (in the case of a non-metallic base material, a backing plated film is additionally provided on the base material) by a dry plating method. A production method for a decorative article having a white film, characterized by comprising a base material shaping process by machining of metal or non-metal, a process of cleaning/degreasing the surface of the base material, a process of bombard-cleaning the base material in a dry plating device (in the case of non-metal, a process of forming a backing plated film on the surface of the base material by a wet or dry plating method after cleaning/degreasing the base material, and a bombard cleaning of the formed film), and a process of forming a white-tone stainless steel film on the surface of the base material (film) by a dry plating method, whereby providing a low-cost decorative article having a white-tone stainless steel film excellent in extended-time corrosion resistance as the outermost-layer film, and a production method therefor.
摘要:
A ductile corrosion and oxidation resistant coating being predominately of gamma-prime nickel aluminide intermetallic includes 15-30 atomic % aluminum, up to 20 atomic % chromium, optionally, up to 30 atomic % of a platinum group metal, optionally, up to 4 atomic % of a reactive element, and optionally, up to 15 atomic % of at least one strengthening element, and a balance being essentially nickel or nickel and at least one of cobalt, iron, or cobalt and iron. A coated article includes the ductile corrosion and oxidation resistant coating on a superalloy substrate such as a turbine disk, turbine seal, a turbine blade, a turbine nozzle, a turbine shroud, or a turbine frame or case having an under platform or non-gas path region.

The present invention relates to a method for producing a flat steel product which comprises a base layer composed of a steel material and a multilayer anti-corrosion coating applied thereto, and to a flat steel product, the method comprising the following operating steps: providing the base layer; applying a zinc layer to the base layer by electrolytic coating; applying an at most 25 nm thick aluminum layer to the surface of the zinc layer, the surface of the zinc layer in regard to the oxides and sulfides present thereon being left in the state existing at the end of the electrolytic zinc coating step or occurring during the course of the aluminum coating step as a result of the method; applying a magnesium layer to the aluminum layer; and subsequently heat treating the flat steel product provided with the coating comprising the zinc layer applied to the base layer, the aluminum layer, and the magnesium layer, in such a way that an MgZn2 layer forms in the coating above the Al layer in the direction of the surface of the coating.
摘要:
The invention relates to a plain bearing composite material with a supporting layer made of steel, a bearing metal layer made of a copper alloy, and with a lining applied to the bearing metal layer. The copper alloy can contain 0.5 5 % by weight of nickel, 0.2 to 2.5 % by weight of silicon and = 0.1 % by weight of lead. The lining can be a sputtered layer that is applied without an intermediate layer. The invention also relates to methods for producing this composite material.
