Abstract
The disclosure provides an aluminized composite including a base material. The aluminized composite may also include a diffusion layer disposed over the base material. The aluminized composite may further include an aluminum material disposed over the diffusion layer.
Claims20
An aluminized composite comprising:
- a base material;
- a diffusion layer disposed on the base material;
- and
- an aluminum alloy disposed on the diffusion layer.
1 more element
A method of coloring a base material, the method comprising:
- placing, in a joining device, a stack of layers comprising a base material, a first diffusion layer disposed on a first side of the base material, and a first aluminum layer disposed on the first diffusion layer;
- applying a pressure to the stack of layers;
- and
- heating the stack of layers to a first elevated temperature for a first period of time to join the aluminum layer to the base material.
1 more element
An aluminized composite comprising:
- a base material, and
- an aluminum layer disposed on the base material to form a contact region between the base material and aluminum layer;
- wherein a first portion of the base material is adhesively bonded to a first portion of the aluminum layer in the contact region,
- wherein a second portion of the base material is locally welded to a second portion of the aluminum layer in the contact region, and
- wherein the portion of the aluminum layer opposite the second portion of the contact region has an average grain size the same as the portion of the aluminum layer opposite the first portion of the contact region.
2 more elements
A method of joining an aluminum foil to a base material, the method comprising:
- applying an adhesive between the base material and the aluminum foil to fix the relative position of the base material to the aluminum foil;
- locally welding the base material and the aluminum foil, wherein the portion of the aluminum layer opposite the second portion of the contact region has an average grain size the same as the portion of the aluminum layer opposite the first portion of the contact region.
