摘要： A copper/aluminum joined structure having a hot-dip- aluminized steel sheet (1) and, laminated thereon by spot welding, aluminum or an aluminum alloy (2), wherein a plating layer (4) comprises 3 to 12 mass % of Si and 0.5 to 5 mass % of Fe, the area percentage of an Al-Fe binary alloy layer (7) in its joining interface is suppressed to 90 % or less, and a region (9) having no alloy layer appears between an Al-Fe-Si ternary alloy layer (6) being present in a base steel (5)/plating layer (4) interface and the Al-Fe binary alloy layer (7); and the above copper/aluminum joined structure which uses a plated steel sheet (1) having a base steel(5) comprising 0.002 to 0.020 mass % of N and having an N-rich layer containing 3.0 atomic % or more of N formed on its surface contacting with the hot dip aluminizing layer (4). The above copper/aluminum joined structure, particularly, the latter one is inhibited in the extension of the Al-Fe binary alloy layer (7), which is low in strength, and as a result, exhibits improved steel/aluminum joining strength.

摘要： The invention relates to an aqueous composition and a method for corrosion protective conversion treatment of metal surfaces. The aqueous composition is particularly suitable for the treatment of various metal materials, joined in composite structures, amongst others of steel or galvanised steel or the alloys thereof and any of combination of said materials, the composite structure being at least partly made from aluminium or alloys thereof. According to the invention, the aqueous composition based on a phosphating solution contains in addition to water-soluble compounds of zirconium and titanium an amount of free fluoride in a ratio that permits the phosphatising of the steel and galvanised steel or the alloys thereof and also a low etching rate of the aluminium surface with concomitant passivation of the aluminium surface. The metal materials, components and composite structures subjected to the conversion treatment according to the invention are applicable in automobile chassis production, in ship building, in civil engineering and the production of white goods.

摘要： The invention relates to a metal multi-layered film structure, comprising two types of metal films including first metal films and second metal films alternately formed on a resin substrate. The first metal films are composed of an aluminum-based material having a film thickness between 0.7 nm and 20 nm. The second metal films are composed of one selected from the group consisting of stainless steel-based materials, nickel-based materials, cobalt-based materials, titanium-based materials and chromium-based materials, having a film thickness ranging from 1 nm to 20 nm. This metal multi-layered film structure can be manufactured through a method of sputtering. The metal multi-layered film structure is suitable for an extension reflector for vehicular lamps.
