A preparation method for adhesive bonding of magnesium-containing aluminum alloy products includes a magnesium-containing aluminum alloy product including a matrix and a surface oxide layer overlying the matrix. The magnesium-containing aluminum alloy product also includes intermetallic particles at least proximal the surface oxide layer. The method also includes ablating at least some of the intermetallic particles via an energy source, and in the absence of melting of the matrix of the magnesium-containing aluminum alloy product.

Preparation of 7XXX aluminum alloys for adhesive bonding

Methods of preparing 7xxx aluminum alloy products for adhesive bonding and products made therefrom are disclosed. Generally, the methods include preparing a 7xxx aluminum alloy product for anodizing, then anodizing the 7xxx aluminum alloy product, and then contacting the anodized 7xxx aluminum alloy product with an appropriate chemical to create a functionalized layer. The new 7xxx aluminum alloy products may realize improved shear bonding performance.

Methods of preparing 7xxx aluminum alloys for adhesive bonding, and products relating to the same

Methods of preparing 7xxx aluminum alloy products for adhesive bonding are disclosed. Generally, the methods include chemical and/or mechanically preparing a 7xxx aluminum alloy product to reduce the amount of magnesium oxides while maintaining any copper-containing intermetallic particles located proximal the surface of the 7xxx aluminum alloy product. After preparation, a functionalized layer may be produced thereon for adhesive bonding.

An apparatus and method for applying an EDT texture to an aluminum sheet has a rolling stand with at least one EDT surfaced roll capable of rolling the sheet at reductions &#x3c;1%. The rolling is conducted with residual or no lubrication and imparts a texture on the scale of about 1 &#x3bc;m to the surface of the sheet at low roll force.

Embossing for electro discharge textured sheet

A material handler formed from isotropic textured aluminum sheet rolled by rolls indented with spherical media, such as steel ball bearings, producing a sheet with a low coefficient of friction relative to particulate matter like flour. The slippery sheeting may be used to make tanks, silos, conduits and guides to facilitate storage and flow of the particulate matter.
