Disclosed is a phosphate coating, comprising: a phosphate portion, wherein the phosphate portion comprises pores, wherein the pores are at least partially filled with a corrosion inhibition sealant, wherein the corrosion inhibition sealant comprises: a base, wherein the base comprises a matrix and a metal within the matrix, wherein the metal within the matrix comprises aluminum, an aluminum alloy, zinc, a zinc alloy, magnesium, a magnesium alloy, or a combination thereof and an inhibitor mixed within the base, wherein the inhibitor comprises zinc molybdate, magnesium metasilicate, trivalent chromium, tungstenate, a metal phosphate silicate, or a combination thereof.

Phosphate coating which can be substantially free of hexavalent chromium and methods of making the same

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.

Sealing process for an anodized aluminum-alloy surface

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.

Solution composition and method for single-bath post treatment of substrate

Disclosed is a corrosion inhibition coating, comprising: a base comprising a silicate matrix, wherein aluminum, an aluminum alloy, or a combination thereof, is present within the silicate matrix; and an inhibitor comprising: zinc molybdate, cerium citrate, magnesium metasilicate, a metal phosphate silicate, or a combination thereof, wherein a curing temperature of the corrosion inhibition coating is about 20&#xb0; C. to about 190&#xb0; C., preferably about 20&#xb0; C. to about 120&#xb0; C. Also disclosed is a substrate coated with the corrosion inhibition coating, wherein the substrate is a peened part.

Low temperature-cured corrosion inhibition coating

A method of disposing a corrosion resistant system to a substrate may comprise applying a plating material to the substrate; forming a chemical conversion coating solution by combining a solvent, at least one corrosion inhibitive cation comprising at least one of zinc, calcium, strontium, magnesium, or aluminum, at least one corrosion inhibitive anion comprising at least one of phosphate, molybdate, or silicate, and a complexing agent; and applying the chemical conversion coating solution to the plating material on the substrate.

Anti-corrosion and/or passivation compositions for metal-containing substrates and methods for making, enhancing, and applying the same

A corrosion resistant article including an aluminum substrate and a corrosion-inhibiting cerium based corrosion inhibitor corrosion inhibiting additive on the aluminum substrate, the corrosion inhibiting additive comprising an anodic corrosion inhibitor and a cathodic corrosion inhibitor, the anodic corrosion inhibitor greater than 25 wt % of the total inhibitor.

Corrosion inhibiting additive

Disclosed is a corrosion inhibition coating, comprising: a base comprising a matrix and a metal within the matrix; and an inhibitor comprising: zinc molybdate, cerium citrate, magnesium metasilicate, a metal phosphate silicate, or a combination thereof, wherein the metal within the matrix comprises aluminum, an aluminum alloy, zinc, a zinc alloy, magnesium, a magnesium alloy, or a combination thereof. Also disclosed is a substrate coated with the corrosion inhibition coating.

Chromium-free corrosion inhibition coating

A method of coating a metal article is disclosed that includes immersing a metal article having an exterior anodized layer in a bath containing a chemically active corrosion inhibitor, and applying a voltage to the article during the immersing, the voltage driving the chemically active corrosion inhibitor from the bath into the exterior anodized layer. An article is also disclosed that has a substrate comprising a metal, and a porous anodized layer formed on an exterior surface of the substrate that is infiltrated with a chemically active corrosion inhibitor, the anodized layer having an inward-facing region and an outward-facing region, the anodized layer having a greater concentration of chemically active corrosion inhibitors in the inward-facing region than in the outward-facing region.

Method of sealing an anodized metal article

A corrosion inhibition composition is disclosed comprising a zinc oxide, a zinc phosphate, a calcium silicate, an aluminum phosphate, a zinc calcium strontium aluminum orthophosphate silicate hydrate, a molybdate compound, a silicate compound, and a zinc phthalate compound.

Anti-corrosion and/or passivation composition for metal-containing substrates and methods for making, enhancing, and applying the same

A method for making an environmentally-safe chromium based corrosion resistant coating includes pre-treating a metal substrate, immersing the metal substrate in a trivalent chromium bath which does not contain hexavalent chromium, post-treating the coated metal substrate with an oxidizer, and curing the coated metal substrate in a controlled environment.
