Integrated Assessment of Coating-Steel Substrate Adhesion—Comparison of Mechanical and Ultrasonic Methods
Year: 2025
Type: article
Abstract: Adhesive coatings, including car paints and car putties, have found application in the construction of motor vehicles. This article contains the results of mechanical and ultrasonic tests of the adhesion of the car putty coating to a steel substrate. The main objective of this article is to determine the correlation between mechanical adhesion and the ultrasonic measure of adhesion—the reflection coefficient |r|. The results indicate that with the increase in the value of the coefficient |r|, the mechanical adhesion of the coating to the substrate decreases. The highest average mechanical adhesion of the coating to the substrate was obtained for sandblasted samples and was 2.74 MPa, corresponding to a coefficient reflection value of 0.71. The test results have an important application aspect and may be useful at the stage of assessing the adhesion of adhesive coatings in a non-destructive manner.
