  • Application of electroplate to moving metal by belt plating
    Patent number: 4772361
    Abstract: An anodic belt electroplating apparatus utilizes a flexible, electrolyte permeable belt anode with porous outer belt covering that provides flexible operation parameters. The perforate belt anode such as of valve metal in mesh form, has an electrocatalytic coating and an electrolyte-containing wrap for the outer belt covering. Processing parameters can provide desirable electroplate, such as of metal coils electroplated in strip form through an at least substantially flat and horizontal electroplate zone, at highly desirable plating speeds as well as providing careful control over plate composition and deposition thickness.
    Type: Grant
    Filed: December 4, 1987
    Date of Patent: September 20, 1988
    Inventors: Terry E. Dorsett, David P. Rininger, Thomas G. Strempel
  • Electroplate to moving metal
    Patent number: 4761217
    Abstract: An anodic roller electroplating process utilizes novel anodic roller apparatus and provides flexible operation parameters. The novel anodic roller apparatus comprises a perforate valve metal cylinder such as in mesh form. The cylinder has an electrocatalytic coating and an electrolyte-containing, porous wrap. Processing parameters can provide desirable electroplate, such as of metal coils, at enhanced plating speeds as well as providing carefull control over plate composition and deposition thickness.

  • Temperature resistant coating composite
    Patent number: 4487815
    Abstract: Temperature resistant substrates, and particularly metals such as ferrous metals, coated for corrosion resistance with coatings containing particulate metal and hexavalent chromium-providing substance can now be made further corrosion resistant, as well as having excellent heat resistance, with a coating composite. In the composite, the undercoating contains a boric acid component plus substantial amounts of finely-divided aluminum as particulate metal. As an adjacent top layer, a coating containing silica substance is used.
