Atomistic fracture energy partitioning at a metal-ceramic interface using a nanomolecular monolayer
Abstract
We report an experimental approach to partition the fracture energy of a metal-ceramic interface into work of adhesion and plasticity, unveiling the nanomechanics of interfacial deformation and fracture. We obviate crack path uncertainties by constraining fracture to occur in an interfacial nanomolecular layer through fissure of a single bond type whose strength is varied by adjusting the chemical environment. This approach is adaptable for studying interfacial fracture and related phenomena in diverse materials systems in different thermochemical environments.
