摘要： A method of measuring the adhesion of a coating (2) on a substrate (1),
characterized in that the measurement is made in the air and in that there is applied anultrasonic transducer (3) on the substrate ( 1) by means of a thin layer (7) gel andcalculates a quality factor given by the ratio between the amplitudes of the echoesassociated with the first two reflections on the substrate interface (1) - sheathing (2) aftercrossing the substrate (1) or on the coating interface (2) - air after passage substrate (1)and the coating (2).
