“…The increase in hardness by heat treatment did not improve slurry erosion resistance significantly (e.g. Slurry erosion studies by Zhao et al [11] revealed that dual-phase stainless steel eroded 5.78 times, 2.42 times, and 2.75 times faster than chromia coating with flyash, gypsum, and silica sand slurry, respectively. A significant increase of more than three times increase in erosion resistance was noted by Pugsley and Allen [10] for 25 per cent increase in the hardness of WC-Co alloys.…”

In the present work, the slurry erosion behaviour of weld hardfacing alloys was investigated by systematic variation of identified test parameters and the response data were generated from a suitably designed experimental plan. The identified groups of parameters were operational parameters; velocity, slurry concentration, and particle size of the erodent; and relative hardness of erodent particle and the microstructural parameter, carbide volume fraction (CVF). The slurry erosion experiments of hardfacing alloys with different Cr and C content were conducted using a pot-type slurry erosion tester with silica sand slurry of different concentration over a range of velocities. The slurry erosion volume loss of hardfacing alloys exhibited different trends under different test conditions with identified parameters. The slurry erosion volume loss decreased with increasing CVF and H e /H t , (ratio of hardness of erodent to hardness of target) except under severe erosion test conditions where the reverse trend was observed. An empirical correlation was proposed, in which the slurry erosion rate was expressed as a product of operational parameters, microstructural parameter, and relative hardness of erodent particles. Scanning electron microscopy observations were focused on gaining additional information associated with the mechanism of material removal under different experimental conditions.

“…Solid particle erosion, a typical dynamic wear mode, results from the repeated impact of small, solid particles, which is different from other wear modes . It occurs in various engineering fields, including in automobile, aerospace, marine, and energetics applications such as in desulfurizers of thermal power plants where limestone and gypsum particles bring about not only corrosion but also serious slurry erosion of the pumps and pipelines . In these fields, polymers and polymer composites have been frequently used for their high specific strength and stiffness .…”

A novel hybrid composite SiC foam/SiC particles/EP (denoted as SiC foam /SiC p /EP), consisting of E-51 epoxy resin as the matrix, SiC foam and SiC particles as the reinforcements, was prepared in this work. The slurry erosion properties of SiC foam /SiC p /EP composite and SiC foam /EP (SiC foam/epoxy resin) composite were investigated by using a rotating disc rig. It was found out that SiC foam /SiC p /EP exhibited better mechanical and anti-erosive performance as compared with SiCfoam /EP. SiC particle size had great influence on the mechanical and anti-erosive properties of the hybrid composites. Smaller SiC particles were beneficial to improve the mechanical strength, but inclined to decrease the anti-erosive performance of the composite. In general, the hybrid composite SiC foam /SiC p /EP can be applied potentially with the excellent antierosive performance under the solid particle erosion conditions.

“…Based on the different applications, the researchers have invented different type of RESEARCH laboratory test rigs to identify the slurry erosion wear rate and material removal mechanism under the various operating conditions. They are, Miller Test Apparatus, Jet Impingement Tester [1], Falling Jet Test Apparatus [2], Jet-In-Slit Apparatus [3], Centrifugal Erosion Tester [4], Concentric Cylindrical Test Rig, Coriolis Erosion Tester [5] and Slurry Pot Tester [6]. Slurry erosion wear is a complicated phenomenon to identify the most significant parameter for erosion wear and how much its percentage.…”
