Claims
- 1. A bonded structure comprising a first component having a first surface bonded to a second surface of a second component by a bond layer comprising an adhesion layer having a substantially uniform distribution of metal, silicon, carbon, nitrogen and oxygen species through a thickness of the adhesion layer, whereby the percentages of each of the species deviates by less than 10% through the thickness, and wherein the adhesion layer is formed by curing a liquid composition comprising water; a metal alkoxide selected from the group consisting of Al(OR)3, Ti(OR)4, Zr(OR)4, Ta(OR)3 and Hf(OR)4; an aminoalkoxysilane; and an acid; and wherein the liquid composition comprises a molar ratio of metal alkoxide:aminoalkoxysilane:acid of from about 1:0.5:0.1 to about 1:15:0.8.
- 2. The bonded structure of claim 1 wherein the molar ratio of metal alkoxide:aminoalkoxysilane:acid in the liquid composition is from about 1:1:0.2 to about 1:8:0.5.
- 3. The bonded structure of claim 1 wherein the aminoalkoxysilane comprises one or more of aminoalkoxysilanes selected from the group consisting of aminopropyltrimethoxysilane, aminopropyltriethoxysilane, N-beta-aminoethyl-gamma-propylmethyldimethoxysilane, and N-beta-aminoethyl-gamma-propyltrimethoxysilane.
- 4. The bonded structure of claim 3 wherein the aminoalkoxysilane is aminopropyltrimethoxysilane.
- 5. The bonded structure of claim 1 wherein the liquid composition further comprises a solvent capable of dissolving the metal alkoxide.
- 6. The bonded structure of claim 1 wherein one or both of the first or the second surfaces is a metal surface.
- 7. The bonded structure of claim 1 wherein the metal alkoxide comprises aluminum sec-butoxide.
