Abstract
A method of measuring the adhesion of a coating to a substrate, wherein the measurement is done in air and wherein an ultrasound transducer is applied to the substrate by means of a thin film of gel, and a quality factor is calculated, given by the ratio between the amplitudes of the echoes associated with the first two reflections on the substrate/coating interface after passing through the substrate or on the coating/air interface after passing through the substrate and the coating.
