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.
Claims11
An aluminized composite comprising:
- a base material;
- a diffusion layer comprising Si in an Al matrix disposed on the base material;
- and
- an aluminum alloy disposed on the diffusion layer, wherein the diffusion layer has a melting temperature lower than the aluminum alloy;
- wherein the Si content in the Al matrix is lower than 1.0 atomic %.
2 more elements
A method of coloring a base material, the method comprising:
- placing, in a joining device, a stack of layers comprising the base material, a first diffusion layer comprising Si in an Al matrix disposed on a first side of the base material, and a first aluminum layer disposed on the first diffusion layer, wherein the Si content in the Al matrix is lower than 1.0 atomic %;
- 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.
