Notes:
The aim of this paper is to evaluate the cyclic interfacial strength between thin film and itssubstrate by cyclic nano-indentation tests. The specimen used in this study is PET substrate/ITOcoatings layered specimen. From the indentation load and displacement curve, we proposed anevaluation method for the interfacial strength. The results are good agreement with the interfacialstrength evaluated by peel test. After cyclic indentations, the surface profile was observed by atomicforce microscope. The number of elongates increased with indentation cycles when the indentationload is low, whereas elongates number is almost constant under high load cases. These phenomenacan be explained by simple models. In this study, two types of fracture modes are proposed. They are“subsidiary fracture mode” and “buckling mode”
