Abstract
The current development of surface treatments, which are aimed at improving the cavitation erosion (CE) resistance of the metal parts working under vibration conditions in liquid environments, is reviewed. The ultrasonic-cavitation test, which is a convenient and express method for evaluating the cavitation resistance of materials, is also considered. The CE resistance of the metal samples is mainly tested using the typical ultrasonic-vibration apparatus according to the ASTM G32-10 test standard. The physical mechanism of the surface cavitation destruction based on the vaporous-bubbles’ formation is described and analysed. This analysis allows for a better understanding of the role of the surface-treatment methods and their parameters on the structure and mechanical properties of the near-surface region, helping to enhance the protection against the destructive cavitation effects. Examples are given regarding the effective methods for improving the surface-properties’ finish of various metal materials, viz., coatings methods including microarc oxidation, arc spraying, high-velocity oxygen-fuel deposition, cold spraying, cathode arc plasma deposition, laser surface alloying, and nitriding. Additionally, the methods of surface modification, such as laser surface treatment, friction stir processing, and tungsten inert-gas welding/dressing, are also concluded to be efficient CE inhibitors.
