Abstract: The invention described herein provides an organic-inorganic multilayer coating system comprising an advanced nanostructured layer-by-layer hybrid coating for the corrosion inhibition of metals. Electrochemically-active corrosion inhibitors are adsorbed onto a layer-by-layer assembled organic-inorganic multilayer coating, preferably used in combination with a topcoat sol-gel barrier layer, to provide enhanced corrosion protection of metal substrates.

Abstract: A process for chemical removal of organically- modified silicate (Ormosil) coatings from aluminum alloy substrates without degradation of the underlying metal. An Ormosil film is treated with a zincate solution. The zincate solution dissolves the Ormosil film and deposits a thin, easily-removed layer of zinc onto the aluminum alloy surface, which prevents base-activated dissolution of the underlying metal. The zinc layer may be removed using dilute phosphoric acid, leaving the surface of the aluminum alloy intact. Consequently, the sol-gel coating may be removed while the integrity of the aluminum alloy substrate is maintained.

Abstract: An Ormosil composite coating that provides good corrosion and abrasion resistance of the underlying substrate. The Ormosil composite coating of the present invention is entrapped with a plurality of inorganic particles of a size greater than 1 micron to produce a coating of a sufficient, desired thickness. The coating of the present invention, generally includes an ormosil composite including a plurality of entrapped inorganic particles wherein each of the plurality of inorganic particles is at least one (1) micron in its maximum dimension but not greater than 75 microns (however, a maximum dimension of 5 microns is preferred).
