Abstract
The influence of a corroded layer on the insertion surface of products on the parameters of the transmitted ultrasonic wave and the error of ultrasonic thickness gauges are analyzed. We concept of the wall thic kness of a product in ultrasonic thickness measurement is made more pr ecise, the structure of the corroded layer is analyzed, the existence and important role of interference processes in the layer are confirme d, and a formula is derived for the error of ultrasonic thickness gaug es in this case.
