The resistance of S235JR steel to cavitation erosion

Wear, 2020
Abstract The erosion resistance of S235JR steel to flow cavitation was investigated. In order to understand an influence of steel properties and cavitation intensities on the degradation mechanisms, low-carbon S235JR steel was tested in the as-received state and after thermal treatment (annealing) under four different flow velocities.

Erosion Resistance Testing for Abrasion and Cavitation Resistant Coatings

SSPC 2015 Greencoat, 2015
Abstract Cavitation erosion of the rudder has been a serious problem in the high-speed container ship industry. It is well known that the lifetime of a conventional coating system is about 6 months against cavitation bubble collapse. Although STS 316Lstainless steel has been applied to prevent such a problem, there are several drawbacks ...

Cavitation and Erosion Resistance of Polymeric Materials

Journal of Friction and Wear, 2018
The paper analyzes the results of studies regarding the cavitation-erosion wear resistance exhibited by polyolefins in neutral, acidic, and alkaline model environments. Methods for testing the stability of polymers, measuring the subsurface temperature, and performing photo and video surface wear registration directly in the course of cavitation are ...

On Testing Materials for Cavitation Damage Resistance

Journal of Ship Research, 1964
Recent experiments with a magnetostriction apparatus show that cavitation-damage rate is time dependent. This is confirmed by an analysis of the experimental data obtained in various earlier investigations. There are four zones of damage rate with respect to testing time; namely, (a) incubation, (b) accumulation, (c) attenuation, and (d) steady state ...

Cavitation resistance of copper-based alloys

Metal Science and Heat Treatment of Metals, 1962
1. The cavitation resistance of OTsS 6-6-3 bronze used for components of hydraulic press valves is very low; this alloy should not be used for parts exposed to cavitative action. The low resistance is due to the low strength of this alloy and to the fact that its structure contains lead inclusions. 2. Of the Cu-base alloys tested, the Br.

Development of New Cavitation Resistant Coatings

CONFERENCE 2025
Abstract Damage caused by cavitation is observed on hydro-turbines, pumps, pipes, gates, draft tubes, and outlet conduits. Mitigating the effect of cavitation on structures will reduce cost in repairs and downtime. Traditionally, stainless steel weld overlays are used for cavitation repairs on metallic structures. Welding stainless steel

Cavitation Resistance of Thermal Spray Coatings

International Thermal Spray Conference, 1997
Abstract Cavitation and erosion damage to hydroelectric turbines and pumps can be a major problem. The effectiveness of thermal sprayed cavitation-erosion resistant coatings for hydroelectric turbine and pumps was evaluated. The coatings evaluated were applied using High Velocity Oxyfuel (HVOF) and Plasma Spray systems.

Resistance Against Cavitation Erosion of 14 Chromium Steels

Journal of Lubrication Technology, 1970
Abstract For 14 chromium steels of different composition and structure, cavitation-erosion damage has been studied and interpreted in terms of structure and strength properties. The use of chambered cylindrical specimens ensured a uniform attack from the very beginning of the erosion process and, thus, highly reproducible wear values. As
