The coefficient of friction for atomically clean surfaces of metal-ceramic couples, which reflects interfacial adhesion, was found to correlate with the metal’s total surface energy γ in the real area of contact A (i.e., the product γ A ). The coefficient of friction increased as the total...

When the cores merge and the interfacial bonding is comparable to the strength of bonds inside the crystals, the interface will assume a disordered, amorphous-like structure. At temperatures close to the melting point, only...

Poor bonding is also suspected because the majority of the failure was interfacial in nature; only about 5% of the adhesive fracture surface had epoxy on it. Additionally, it was noted that the bonded side of the skin surfaces exhibited smooth, mirror images of the peel...
