Abstract: A process for producing a multi-layer coating on an electrically conductive surface as a corrosion protection layer and/or as a primer for an organic coating, which is produced by (a) forming a layer of at least one inorganic compound of at least one metal A having a weight per unit area of 0.01 to 10 g/m2 by electrochemical deposition on a conductive surface from a solution containing the metal A in dissolved form, wherein the metal A is a different metal from the main component of a metal on the electrically conductive surface and the inorganic compound contains less than 20 wt % phosphate ions; and (b) forming at least one layer of an organic coating on the layer deposited in stage (a); also disclosed is a metal component comprising a coating comprising at least two layers obtainable in this manner.

Abstract: The present invention relates to electrodeposition material for the electrochemical deposition of a corrosion-protective layer of TiO2 on an electrically conductive substrate comprising a titanium compound, a complexing agent, an accelerator, water and optionally organic solvents, buffering agents and one or more additives, characterized in that the titanium compound is titanyl sulfate and/or titanyl oxalate, the complexing agent is selected from the group consisting of citric acid, citrates, tartaric acid, tartrates, lactic acid, lactates, gluconic acid, gluconates, polyhydroxy-polycarbonic acids, ethylenediaminetetraacetate, methylglycinediacetate, iminodisuccinate, nitrilotriacetic acid and nitrilotriacetate, triethanolamine, phosphonic acid and phosphonates, polyaspartic acid and polyaspartates, polyacrylic acid and polyacrylates and the accelerator is selected from the group consisting of H2O2 and organic peroxides.

Abstract: The present invention relates to a process for providing a metal substrate with corrosion-protection and corrosion-resistance, respectively, as well as to the products thus obtainable. Said process comprises coating said metal substrate with a thin layer of at least one metal oxide selected from the group consisting of TiO2, Bi2O3 and ZnO, preferably TiO2, by electrochemically depositing said metal oxide layer on at least one surface of said metal substrate. At the same time, said metal oxide layer may serve as a primer layer for subsequent coating treatment (e.g. coating with organic materials, such as for instance lacquers, varnishes, paints, organic polymers, adhesives, etc.).
