The non-conductive anodized aluminum ground ladder and the non-conductive anodized aluminum aerial ladder for the fire service uses non-conductive anodic oxide layer coatings in the manufacture of aluminum ground and aerial ladders to provide passive protection to all affected firefighters and civilians they may be rescuing in the event of inadvertent contact with high voltage power lines and/or other high voltage electrical conductors.

A laminate including a metal substrate having a chemically etched surface and a fluoroelastomer layer laminated in contact with the chemically etched surface or laminated in contact with a surface of a fluororesin layer laminated in contact with the chemically etched surface, and a gate valve including the laminate, are provided.

Provided are a laminate including a metal substrate having a surface with an anodic oxide coating formed thereon, a fluororesin layer laminated in contact with the anodic oxide coating and a fluoroelastomer layer laminated in contact with a surface of the fluororesin layer facing away from the metal substrate, and a gate seal including the laminate.

Disclosed is a method of treating a surface of an aluminum material, the method including: degreasing an aluminum material; etching the degreased aluminum material; performing a first desmutting treatment by immersing the etched aluminum material in a 25-35 wt % nitric acid solution at a temperature in a range of 25 to 30 C. for at least 60 seconds; performing a second desmutting treatment by immersing the first desmutting-treated aluminum material in a 5-15 wt % nitric acid solution at a temperature in a range of 25 to 30 C. for a time in a range of 30 seconds to 60 seconds; anodizing the second desmutting-treated aluminum material; coloring the anodized aluminum material; and sealing the colored aluminum material.

Anodized electroplated aluminum structures and methods for making the same are disclosed. Cosmetic structures according to embodiments of the invention are provided by electroplating a non-cosmetic structure with aluminum and then anodizing the electroplated aluminum. This produces cosmetic structures that may possess desired structural and cosmetic properties and that may be suitable for use as housing or support members of electronic devices.

A pattern forming method is disclosed. The pattern forming method includes buffing a surface of a product containing aluminum, masking at least a part of the buffed surface with an etching resist, etching a part of the buffed surface not masked by the etching resist, removing the etching resist from the surface, and anodizing the surface from which the etching resist is removed.

A method of treating a surface of an aluminum busbar includes pre-conditioning the surface of the busbar, anodizing one portion of the surface of the busbar, and plating another portion of the surface of the busbar with at least one metal. A fixture used to secure a busbar for a treatment process is also disclosed.

A method for the manufacture of plastic components that are corrosion-stable, optionally coated in metallic color and decorative first manufactures the components to be coated from a galvanizable plastic in the plastic injection-molding process and then subjects them to a chemical pretreatment, in which a first conductive metal layer is deposited and then an aluminum surface is deposited galvanically. The deposited aluminum surface is oxidized in a subsequent aluminum anodization process.
