Quality control of protective polymer coatings on metal by acoustic method

Abstract

Abstract An acoustic method for quality control of adhesive compounds of polymer coating on metal in the coating—positive system qualitatively characterizing the value of the adhesive bond is proposed. Ultrasonic measuring cell is considered as a resonant system, the parameters of which are determined by the properties of all the parameters of the layered structure at the same properties of the piezoelectric sensor and acoustic contact. The coating adhesion is evaluated on the basis of the parameters of the amplitude-frequency characteristics of the studied layered structure of the composite coating according to the humming dependences of the adhesion — reflection coefficient the wave. The technique allows to control the processes of polymerization of organic coatings in the process of their formation.
