INVESTIGATIONS OF COHESIVE ZONE PROPERTIES OF THE INTERFACE BETWEEN METAL FILM AND CERAMIC UBSTRATE AT NANO- AND MICRO-SCALES

摘要：

Cohesive zone characterizations of the interface between metal film and ceramic substrate at micro-and nano-scales are performed in the present research.At the nano-scale,a special potential for special material interface (Ag/MgO) is adopted to investigate the interface separation mechanism by using MD simulation,and stress-separation relationship will be obtained.At the micro-scale,peeling experiment is performed for the Al film/Al2O3 substrate system with an adhesive layer at the interface.Adhesive is a mixture of epoxy and polyimide with mass ratio 1:1,by which a brittle cohesive property is obtained.The relationships between energy release rate,the film thickness and the adhesive layer thickness are measured during the steady-state peeling.The experimental result has a similar trend as modeling result for a weak adhesion interface case.
