The erosion of metals
The study of the erosion of metallic surfaces by solid particles has been an area of dispute recently (1980) especially concerning the importance of target melting as a mechanism for the removal of material. In addition, erosion by particles at a normal angle of impingement has remained unexplained …

Cavitation erosion of materials
… fluids and materials for combating cavitation erosion in hydraulic mining machinery operating,on 5:95 oil-in-water emulsions, Controlled cavitation was generated in the laboratory in a vibratory cavitation apparatus employing the stationery specimen system. The influence of separation distance …

The erosion of materials
Solid particle erosion tests of glass, stainless steel, WC-Co and sintered alumina, have been performed with seven erodents using a range of particle diameters D (63 μm - 1000 μm), velocities V (33 m.s⁻¹ - 131 m.s⁻¹ ) and impact angles α (30° - 90°). The seven erodents are steel shot, glass beads, …

Erosion-corrosion mitigation using chemicals
… prevalent as wells age and this is leading to erosion-corrosion in C02-saturated conditions becoming a major mechanism of material attack. Its understanding, prediction and control are key challenges to sound facilities design. The use of carbon steel in conjunction with corrosion inhibitors in …

Cavitation erosion of engineering materials
… in this thesis is concerned with evaluating the erosion resistance or behaviour of various engineering materials to cavitation erosion in a through flow device. A wide range of engineering materials have been utilized, from metal alloys, plastics, ceramics to composiles. These were procured from …

Erosion surfaces in northwestern Maine
In the progress of Boston University's geological mapping program in the Rangeley Lake region of northwestern Maine the occurrence of conspicuously level areas at varying, yet definite elevations was noted. Essentially horizontal or but slightly inclined areas, independent of structure and …

Solid particle erosion of ceramics
The zeolite ZSM-5 is well-known for its unique intersecting channel system. This channel system has a great bearing on the shape-selective properties and the long life-times of ZSM-5. In this study, ZSM-5 was modified in various ways to eliminate the external acidity of the catalyst to further …

Cavitation erosion of WC-Co
… investigation involving the vibratory cavitation erosion of WC-Co alloys was undertaken in order to determine the mechanisms of material removal. Nineteen grades of WC-Co alloys were studied. These alloys had been previously characterised according to microstructural and mechanical properties. …

The erosion of ultrafine WC-Co
… have been characterised and subjected to slurry erosion and cavitation erosion. A further twelve WC-Co alloys of varying grain sizes and cobalt contents have been produced through conventional processes and subjected to the same tests in order to provide data for comparison. The erosion …

The erosion of WC-Co coatings
A study has been conducted on both the particle and slurry erosive wear behaviour of WC-Co hard metal coatings. The coating compositions were WC-12%Co and WC-10%Co-4%Cr and were produced using both the TAFA JP5000 and the METCO Diamond Jet (DJ) thermal spray systems.

Streambank erosion: mechanisms and mitigation techniques
… a study of the various mechanisms that may cause erosion of streambanks and the corresponding mitigation techniques used to combat them. The determination of each may depend upon a number of considerations. The source of the information comes from a variety of reports and papers, which are …
