  • Patent number: 4952287
    Abstract: Electrolytic galvanizing process in which steel strip to be zinc coated is passed continuously through an acid electrolyte solution containing zinc ions and is used as a cathode, while the electrolyte solution is made to flow in the space between the cathode and the anode, in a cell having flat parallel electrodes. The plating current density and the fluid dynamic conditions of the electrolyte are related by the equationI=K C Re.sup.nin which I is 15-300 A/dm.sup.2, K is 0.01-0.0001 A/dm.sup.2 l/g, C is 40-80 grams of zinc per liter of electrolyte solution, Re is the Reynolds number between 1,000 and 200,000, and n is 0.55-0.85. Preferred values are K=0.001, C=80 g/l and n is 0.7.

  • Patent number: 4875983
    Abstract: In the continuous electrodeposition of chromium metal and chromium oxide on metal surfaces the codeposition of chromium and its oxide, inert and insoluble, is obtained from the same bath and at high current density, by using a number of cycles of impressed cathodic current and defined ranges of electrolyte velocities in the deposition cell. In this manner a product is obtained wherein a specific quantitative relationship between chromium metal and chromium oxide ensures corrosion resistance superior to that obtainable in known products.
