Abstract: Described herein are anodized continuous coils containing a thin anodized film layer and systems and methods for making and using the same. The anodized continuous coils include an aluminum alloy continuous coil, wherein a surface of the aluminum alloy continuous coil comprises a thin anodized film layer and a chemical additive layer. The thin anodized film layer can be a dielectric for electronic device applications.

Abstract: Provided herein are corrosion resistant metal substrates and methods for producing the same by thermal modification. The disclosure provides methods for producing corrosion resistant substrates by producing a pretreatment film on a surface of a metal substrate and heating the pretreated metal substrate. In particular, the metal substrate and/or the pretreated metal substrate of these methods is in an F temper, a T4 temper, or a T6 temper.

Abstract: Described are aluminum alloy products that generally have a microstructure and composition that resists corrosion. This corrosion resistance, in turn, allows the aluminum alloy products to exhibit favorable bond durability performance, such as when adhesively bonded to another product. The corrosion resistance can be achieved by controlling the composition of the aluminum alloy, including the presence and/or concentration of certain intermetallic particles, such as α-phase intermetallic particles and β-phase intermetallic particles.

Abstract: Disclosed herein are systems and methods for engineering a metal substrate surface via a dry chemical deposition technique. Also described herein are the resulting surface engineered metal substrates. More particularly, disclosed are surface engineered metal substrates having thin films deposited via flame pyrolysis of a mixture of a gas mixture comprising an oxidizer and a combustible gas, a chemical precursor comprising a silicon-containing compound and/or a phosphorus-containing compound, and a chemical additive.
