Abstract

This paper presents a novel technique to investigate coating adhesion using a radial speckle interferometer and a microindentation test. The proposed technique is based on the measurement of the radial in-plane displacement field produced by a microindentation introduced on the coated surface of the specimen. The advantages and limitations of the proposed technique are shown.
