Cross-sectional indentation technique for thick film interfacial adhesion characterisation

Résumé

The adhesion strength of ceramic/metal interface plays an important role on the reliability of many engineering components. In the present study, the cross-sectional indentation technique is used to determine the interface adhesion of a thick silver film on barium titanate substrate. The test introduces a Vickers micro-indentation at the brittle substrate close to its interface; a small substrate chip is produced to push the thick film laterally and delaminate it from the substrate. The average strength value for the Ag/BaTiO3 interface varies from 2 to 4 J m(-2). This is close to the value obtained using a blister technique.
