The plate is then subjected to a drying-oxidating treatment in air. The plate may be steel having a thickness between 0.1 and 2 mm. The plate may be surface treated by phosphating, and then painted. The chrome-chromic oxide coating may have a thickness between 0.05 and 5 .mu.m, and the zinc coating a thickness between 1 and 30 .mu.m.

  • Patent number: 4495254
    Abstract: The surface of a metal article which is exposed to the atmosphere and abrasion during normal use of the article is protected from scratches and/or corrosion during such use by a thin transparent abrasion-resistant film of an inert non-metallic material such as SiO.sub.2, SiC, Si.sub.3 N.sub.4, TiO.sub.2, MgO, Al.sub.2 O.sub.3, Ta.sub.2 O.sub.5, Nb.sub.2 O.sub.5, GeO.sub.2, spinel and selected colorless glass compositions. The protective film is preferably deposited by RF-sputtering techniques and undesirable coloration of the article by optical interference effects from incident light rays is avoided by properly correlating the film thickness with the refractive index of the particular material used to form the film. The invention permits the use of thinner gold plating on such items as articles of expensive jewelry and bracelets and cases for fine wristwatches without detracting from the quality, durability or appearance of the merchandise.

  • Patent number: 4411963
    Abstract: A thin film of magnetic recording material is sputter deposited over a base layer of gold and tantalum on a polished substrate. A protective layer of gold and tantalum is deposited overlaying the magnetic recording film. A solid lubricant layer such as carbon, preferably in the form of graphite, gold, silver, tin, molybdenum disulfide, and tungsten disulfide is sputter deposited or ion plated over the protective layer to reduce wear. The recording contacting portion of the recording head is similarly coated with a solid lubricant material. Other suitable protective materials include tantalum, niobium, tungsten and nitrides and carbides of such metals. In a preferred method for making such recording members, the layers are successively sputter deposited in an evacuated sputter chamber, whereby the recording layers and protective coatings are formed in a continuous process requiring only one pump down.

    Abstract: A method of applying solder to gold by applying a gold-tin intermediate layer to the gold and applying the solder over at least a portion of the intermediate layer. The method can be employed to produce a printed circuit unit composed of a printed circuit board, at least one gold member mounted on the board, a gold-tin intermediate layer bonded to at least a portion of the gold member, and solder bonded onto the intermediate layer.

  • Patent number: 4268584
    Abstract: A laminated conductor includes a lower thin film of nickel-X alloy or pseudo alloy deposited upon a substrate containing silicon or upon a substrate intended for use as a magnetic bubble storage device. Upon the film of nickel-X alloy, a thicker film of gold is deposited as the conductive portion of the conductor. On the upper surface of the gold layer is deposited a thin film of nickel-X alloy. Failure of the conductor because of electromigration is reduced dramatically as compared with use of molybdenum instead of nickel in the laminated structure. The nonmagnetic nickel-X alloy does not interfere with magnetic fields or produce unwanted magnetic fields.

  • Patent number: 4124736
    Abstract: It is known to manufacture a recording member having a substrate supporting a magnetic recording alloy on a surface and to locate a protective covering on the surface of the alloy remote from the substrate. An improved protective covering for use in this combination comprises a barrier layer located on the surface of the recording alloy and an oxide layer located on the surface of the barrier layer remote from the recording alloy. The barrier layer preferably consists of a nonmagnetic material. The oxide layer is also nonmagnetic and is sufficiently thick to protect the magnetic alloy layer against surface abrasion. The barrier layer isolates the oxide layer from the magnetic recording layer so as to preserve the character and uniformity of the magnetic recording layer as the oxide layer is created.
