G. Wang et Jj. Lannutti, CHEMICAL THERMODYNAMICS AS A PREDICTIVE TOOL IN THE REACTIVE METAL BRAZING OF CERAMICS, Metallurgical and materials transactions. A, Physical metallurgy andmaterials science, 26(6), 1995, pp. 1499-1505
Thermodynamics have long been applied to our understanding of the reac
tive wetting phenomena in metal-ceramic joining. We postulate the exis
tence of a ''solvent effect'' due to the interaction between the react
ive element addition and the brazing alloy. This effect plays a signif
icant role in reactive wetting. By taking this effect into account, mo
re realistic reactivities of different reactive element additions into
a given brazing base alloy are predicted. Irreversible thermodynamics
are also used to characterize the driving forces for reactive metal-c
eramic joining.
