Abstract:
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.
