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 ...

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 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.

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

Cavitation and resistance to water flow in plant roots

Agricultural Meteorology, 1977
Abstract Large variations in resistance to water flow in plants may be caused by cavitation in root xylem. A relationship is found between resistance to air flow through frozen cotton root segments and stress in the plant from which the segment was taken, thus suggesting a possible method of deducing cavitation and its effect on plant resistance.

Mechanical Properties of Metals and Their Cavitation-Damage Resistance

Journal of Ship Research, 1966
Detailed investigations with a magnetostriction apparatus were carried out to determine the cavitation-damage resistance of eleven metals in distilled water at 80 F. The cavitation-damage resistance is defined as the reciprocal of the rate of volume loss for a given metal.

Investigating Polymeric Elastomers for Cavitation and Erosion Resistance

Materials Performance
Cavitation and erosion damage are observed on water infrastructure. Mitigating degradation on mild steel traditionally includes stainless-steel weld overlays, which create a galvanic corrosion cell in immersion conditions. This can cause delamination of the stainless steel and subsequent loss of cavitation or erosion protection.
