Patent ID: 8889226

Claim:
A method of bonding a metal to a substrate, comprising: forming a nano-brush on a surface of the substrate, the nano-brush including a plurality of nano-wires extending above the substrate surface, the forming of the nano-brush including: forming a plurality of nano-pores in the surface of the substrate; depositing a material into the plurality of nano-pores; growing a nano-wire in each of the plurality of nano-pores from the deposited material; and removing a portion of the substrate surface to expose the nano-wire grown therein; in a molten state, introducing the metal onto the substrate surface, the metal penetrating spaces between each individual nano-wire in the plurality of nano-wires and surrounding each individual nano-wire in the plurality of nano-wires; and upon cooling, solidifying the metal surrounding each individual nano-wire in the plurality of nano-wires, wherein during the solidifying, forming at least a mechanical interlock between the metal and the substrate.
