Abstract
An assembly includes a first member, a second member adjacent to the first member, and an aluminum material. At least one of the first member and the second member defines at least one trench. The aluminum material is disposed within the trench and bonds the first member to the second member along adjacent faces. In one form, a spacing between the first member and the second member along the adjacent faces is less than 5 μm.
Claims23
An assembly comprising:
- a first member;
- a second member disposed adjacent to the first member,
- wherein at least one of the first member and the second member defines at least one trench;
- and
- an aluminum material disposed within the trench and bonding the first member to the second member along adjacent faces,
- wherein a spacing between the first member and the second member along the adjacent faces is less than 5 μm.
3 more elements
A method of joining comprising:
- preparing a first member;
- preparing a second member;
- forming at least one trench in at least one of the first member or the second member;
- placing a strip of solid aluminum material between the first member and the second member across the trench;
- bringing the first member and the second member together to contact the solid aluminum material and to form an assembly;
- applying a force and heat to the assembly above a melting point of the solid aluminum material such that the solid aluminum material flows into the trench;
- applying additional heat to the assembly at or above a wetting temperature of the member in which the trench is formed to bond the first member to the second member along adjacent faces;
- and
- cooling the assembly,
- wherein a spacing between the first member and the second member along the adjacent faces is less than 5 μm.
7 more elements
An assembly comprising:
- a first ceramic member;
- a second ceramic member disposed adjacent to the first member,
- wherein at least one of the first ceramic member and the second ceramic member defines a plurality of trenches spaced a distance apart less than 2 mm;
- and
- an aluminum material disposed within the plurality of trenches and bonding the first ceramic member to the second ceramic member along adjacent faces,
- wherein a spacing between the first member and the second member along the adjacent faces is less than 5 μm.
