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 …

The solid particle erosion of WC-Co alloys
An investigation involving the erosion of WC-Co alloys by solid particle impact erosion was undertaken to determine the mechanism by which material is removed. For this purpose a simple particle-gas stream erosion apparatus was employed. The nineteen different WC-Co alloys studied were initially …

The Solid Particle Erosion of Polycrystalline Diamond at High and Low Temperatures
… the research presented in this thesis, solid particle erosion (SPE) has been used to simulate wear in freestanding PCD discs. The objective was to investigate how PCD responded to SPE over a range of conditions and at both ambient and high temperatures. Experiments were performed on …

Test rig design to simulate ashlock valve erosion in coal gasification systems
The erosion of ashlock hopper valves in coal gasification systems, and the maintainance downtime resulting from this erosion, is a cause of considerable concern to the coal conversion industry. After an assessment of the factors considered relevant to solid particle erosion as presented in …

The effects of properties, microstructure and phase transformation on the erosion of hard materials
… ultrahard materials have been subjected to both solid particle and cavitation erosion. The materials tested include three grain sizes of alumina, stabilised zirconias, sialon, cubic boron nitride and polycrystalline diamond, and these have a range of microstructural, physical and mechanical …

Failure mechanisms in impact erosion of ductile materials
Solid particle erosion in ductile materials is a common problem in many industrial applications. It is defined as material loss resulting from the mechanical contact between the particle and the metal surface. Many experimental studies were reported in the past to determine the loss of the material …

CFD-based erosion modelling of simple and complex geometries
… of reducing their product's susceptibility to solid particle erosion. A CFD-based erosion modelling tool is achieved by first solving the fluid flow through the component of interest; tracking particles through the fluid and extracting impact data on all solid surfaces; and finally relating the …

The tribological behaviour of aluminium matrix composites
… by their ability to resist indentation by hard particles. Abrasion against fine grit particles leads to a reduced load per abrasive particle and a correspondingly significant reduction in wear loss. Reciprocating sliding wear tests, conducted in an aqueous environment and against hardened steel …

Erosion - corrosion mechanisms of stainless steel UNS S31603
Solid particle erosion-corrosion is the wear caused by the combined action of the mechanical process of solid particle erosion and the electrochemical process of corrosion. This joint action leads to a synergistic interaction that enhances the wear rate of the material, causing severe problems to …

The erosion of titanium aluminide intermetallic alloys
The erosion behaviour of titanium aluminide intermetallic alloys has not been widely reported in the scientific literature and is part of the current international research effort aimed at exploiting these materials for turbine engine and automotive applications. In the present study titanium …

Glass ceramics from a South African pulverised fuel ash
… properties of the materials were tested by solid particle erosion, and the materials ranked against a selection of other materials used for their wear resistance.

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, …
