Abstract

The paper presents an ultrasonic vibration method for laboratory testing of the resistance of materials to the effect of cavitation. The description of the test method and device, the test procedure, and the interpretation of test results are given in accordance with ASTM G32 standard. A comparative overview of the test results of different types of materials is presented: metal (steel, aluminium alloys); ceramics (based on pure and mixed refractory fillers); composite materials with a polymer base; refractory castings and protective coatings. Based on the test results, the correlation of structural characteristics, mechanical properties of materials are determined as a basis for quick selection of materials in hydrodynamic conditions of application.

Keywords: • cavitation resistance • metallic and non-metallic materials • mass loss • choice of materials
