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.

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, the at least one trench defining a depth and a width;
- 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, and the width of the at least one trench is between 5 and 20 times the depth of the at least one trench.

An assembly comprising:
- a first ceramic member;
- a second ceramic member disposed adjacent to the first ceramic 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, the plurality of trenches each define a depth and a width, and the width of each trench is between 5 and 20 times the depth of each trench;
- 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 ceramic member and the second ceramic member along the adjacent faces is less than 5 μm and a surface roughness of the adjacent faces of the first and second ceramic members is between 5 μm and 100 nanometers.
