Abstract

The structure and the principle of ultrasonic non-destructive testing system of journal bearings are described in this article. The testing principle is based on the influence of adhesion quality on the amplitude of ultrasonic signal, reflected from the interface between layer and main metal. The measurements are performed using pulse response technique with 5 MHz immpersion transducers. The developed ultrasonic system consist of the electronic unit, scanner, testing tank and IBM PC type computer with specialized software. The test results can be presented in the usual A, B, C scan modes imcluding options of signal processing, which allow determine the zones of delamination. The experimental results and the method for the evaluation of the total area of detectyed zones of delamination are presented also.
