Influence of Products’ Surface Roughness on Results of Ultrasonic Inspection with the Use of Piezoelectric Transducers

G. Ya. Dymkin, V. P. Lohov

Results of experimental researches on influence of surface roughness on sensitivity when using ultrasonic testing method with the use of direct piezoelectric transducer are given. It is shown that it is more reasonable to use piezoelectric transducers with polyurethane treads or thin polyurethane intermediate films.
