Abstract: Disclosed is a solution composition which may be used for a single-bath electrochemical passivation and a method using the same. The solution composition includes a metal cation, a metal-oxide anion; and an organic ligand, and optionally includes a non-metallic oxide anion or a polymer. The solution composition may prevent undesired precipitation of metal oxides before performing passivation. In addition, the method of passivation using the solution composition in a single-bath use is also provided.

Abstract: A sealing process includes applying a first reactant to a substrate having a porous structure, the first reactant comprising a chromium (III) precursor and a transition metal precursor and applying a second reactant to the first reactant, the second reactant comprising a rare earth element precursor and an alkaline earth element precursor to form reservoirs of trivalent chromium in pore space of the porous structure, and a physical barrier over the substrate and the reservoirs.

Abstract: A method for preparing a hybrid inorganic-organic nanostructured inhibitive pigment, includes premixing a first stock solution containing one or more cations and a second stock solution containing one or more oxoanions to form a premixture under pH control in the presence of polymers as surface modifiers. The premixture is then reacted to form a slurry. The slurry is then quenched to separate nanoparticles from the slurry, followed by surface functionalization in organic inhibitors.

Abstract: A metal article comprises an alloy substrate having a surface and a non-diffused metal monolayer disposed thereon. The surface has a first surface work function value Φs. The non-diffused monolayer deposited on the surface has a second surface work function value Φs that is less negative than the first surface work function value. A method for depositing the monolayer via underpotential deposition (UPD) is also disclosed.
