Claims
- 1. An article of manufacture performed by the process of:
- (a) providing an alloy comprising a first alloy component of about 0.5 to 12% aluminum and the balance being selected from a material from the group consisting of copper and iron;
- (b) heating said alloy at a temperature below about 350.degree. C. in an oxygen-rich atmosphere to form a oxide layer of said material on a surface of said alloy; and
- (c) heating said alloy at a temperature between approximately 500.degree. to 850.degree. C. in a reducing atmosphere to reduce said oxygen layer of said material into a layer of said material and to simultaneously form an aluminum oxide layer between said layer of said material and the surface of said alloy.
- 2. The article of claim 1 wherein said material is copper.
- 3. An article of manufacture formed by the steps of:
- (a) providing an alloy comprising a first alloy component of about 0.5 to 12% aluminum and the balance being selected from a material from the group consisting of copper and iron;
- (b) heating said alloy at a temperature below about 350.degree. C. in an oxygen-rich atmosphere to form an oxide layer of said material on a surface of said alloy; and
- (c) heating said alloy at a temperature above about 500.degree. C. in a reducing atmosphere to reduce said oxygen layer of said material into a layer of said material and to simultaneously form an aluminum oxide layer between said layer of said material and the surface of said alloy.
- 4. A composite comprising:
- a first alloy component of about 0.5 to 12% aluminum and the balance selected from a material of the group consisting of copper and iron;
- a second component comprising a layer of said material; and
- an aluminum oxide layer between said first component and said second component.
- 5. The composite of claim 4 wherein said first alloy component further includes a second alloy component comprising about 0.001 to 6% silicon.
- 6. The composite of claim 5 wherein said material is copper.
- 7. The composite of claim 6 wherein said first alloy component comprises 2.5 to 3.1% aluminum and said second alloy component comprises 1.5 to 2.1% silicon.
- 8. The composite of claim 4 wherein said material is iron.
