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 ...

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

A metallurgical approach to improved cavitation-erosion resistance

Journal of Materials Engineering and Performance, 1997
Although cavitation erosion in hydraulic systems is an old problem, the damage mechanism that culminates in material loss was not known with certainty until recently. An investigation is described that aimed at clarifying the damage mechanism in cavitation erosion and applying that knowledge to make hydraulic equipment more resistant to cavitation ...

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 ...

Investigation of Polymeric Elastomers for Cavitation and Erosion Resistance

CONFERENCE 2023, 2023
Abstract Damage caused by cavitation and erosion is observed on hydro-turbines, pumps, pipes, gates, draft tubes, and outlet conduits. Mitigating the effects of this degradation on metallic hydraulic steel structures will reduce downtime and costly repairs.

The Resistance to Cavitation Erosion of CrMnN Stainless Steels

Journal of Materials Engineering and Performance, 1998
The resistance to cavitation erosion (CE) was measured using a magnetostrictive device and a rotating disk device for some CrMnN stainless steels (Chinese patent ZL 90 1 02197.0). The microstructural changes in the surface layer before and after CE were analyzed by use of Mossbauer spectra.

Resistance to wear and cavitation erosion of bearing alloys

Wear, 1986
Sliding wear and vibratory cavitation erosion tests in paraffin oil were carried out on bearing alloys, i.e. tin-based and lead-based white metals, Cu-Pb alloy and leaded bronze. In lubricated wear under mild conditions the surface is worn smooth and a slight difference exists between the wear resistances of the four alloys.

Cavitation erosion resistance of various material systems

Ships and Offshore Structures, 2006
Abstract Advancement in both the design and construction of high-speed ships necessitates the evaluation of cavitation erosion resistant materials. Given their weight advantages, aluminum and laminated composite materials are often chosen as construction materials for high-speed designs.

Cavitation erosion resistance of ZrC nanoceramic coating

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2019
A ZrC nanoceramic coating was prepared on the bare 316 stainless steel for improving the cavitation erosion resistance by the double glow discharge sputter technique. The phase constitution and surface microstructure of the ZrC nanoceramic coating were characterized by X-ray diffraction, scanning electron microscope, and ...
