Abstract

The problems of ensuring the durability of ultrasonic  technological equipment is considered in article. The results of the experiment planning are presented, which made it possible to correctly construct a field study and select construction materials. Experimental materials such as 30ХГСА, СЧ20, Ф4, 08Х18Н10Т and ЛС59_1П were chosen for the field experiment, because all these construction materials have similar values of the Young's modulus. The course and carrying out of full-scale experimental research of erosion destruction of the declared constructional materials from which ultrasonic radiators and details of cavitation chambers can be made are shown. The behavior of the studied samples and the dependence of their weight loss on the processing time at different capacities of the ultrasonic reactor are analyzed. The study identified the best materials in terms of cavitation strength in the presence of fatigue stresses.
