Ceramic microstructure and adhesion [PDF]

open access: yesJournal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1985
When a ceramic is brought into contact with a ceramic, a polymer, or a metal, strong bond forces can develop between the materials. The bonding forces will depend upon the state of the surfaces, cleanliness and the fundamental properties of the two solids, both surface and bulk.
