“…Erosion rate was calculated using the formula below: In the present study, the impingement velocities of erodent particles were measured with respect to acceleration/blast gun pressure and particle size by using a double disk method. The double disk method is known as the most widely used method to measure the impingement velocities of particles [11][12][13][14][15][16][17]. Figure 4 shows a schematic illustration of the double disk method used in this study.…”

Polymethyl methacrylate (PMMA) is one of the most popular synthetic polymers in aircraft windshields as an alternative to glass, due to its lightweight, high transparency and impact-resistant characteristics. The erosion behavior of PMMA is critical when used as an alternative to glass in an aircraft windshield. This paper presents experimental data on the effects of particle size, velocity and impingement angle on the roughness of PMMA, using 3D optical profilometry after solid particle erosion tests. Particular attention is paid to determining the different morphologies of imprints and cracks with regard to particle size, impact velocity and impingement angle. It is further shown that the removed volume in overlapping impacts measured by 3D profilometry is captured well. It is demonstrated that maximum erosion rate occurred at a 30° impingement angle and correlates well with the ductile erosion behavior of PMMA. Detailed worn surface analysis was performed using 3D optical profilometer scanning to investigate effects of particle size, velocity and impingement angle on the roughness of PMMA.

“…The erosion wear of slurry pipelines results from two mechanisms, particle impact and scouring, where the latter occurs as a result of a sliding abrasive wear. Several apparatuses have been introduced to study the wear mechanism of slurry pipes [12,13]. These apparatuses aim to study the influence of multiple factors like the flow concentration, the particle size, or the flow velocity.…”

Abstract:The wear of pipelines, used in slurry transport, results in high costs for maintenance and replacement. The wear mechanism involves abrasion, corrosion, impact, and the interaction among them. In this work, we study the effect of impact on the wear mechanism and wear rate. Results show that when the effect of impact is small, the wear mechanism is dominated by electrochemically induced surface modification, which leads to a lower wear rate in a corrosive environment than in a non-corrosive environment. By contrast, when the effect of impact is large, the wear mechanism is drastically altered. In that regime plastic deformation is important. The influence of corrosion in the high impact regime can be neglected. Our findings show the importance of including impact effect in the distinction of wear of slurry pipes.

“…Selection of proper material [4], processing techniques [5] and heat treatment [6,7], eects the erosion resistance. Investigations and studies provide insight into the mechanisms of material removal during the wear process of material [8]. There are a number of methods to evaluate the erosion wear of materials using equipment, such as small feed rate erosion test equipment [9], particle jet erosion test equipment [10], coriolis erosion tester [11] and slinger erosion test equipment [12].…”

In this study, the solid particle erosion behavior of solutionized, articially aged (T6) and annealed aluminum alloy AA7075 has been investigated. The samples were eroded in solid particle erosion test equipment at 45• impingement angle and 75 m/s impingement velocity with 180 mesh garnet erodent particles. Afterwards, microstructures of solutionized, articially aged and annealed samples of AA7075 alloy were analyzed. In order to gure out the eect of ductility on erosion rates, the Brinell hardness of the samples was measured. The surface morphology images of the samples were taken before and after the erosion test by using scanning electron microscope (SEM). The eects of the microstructures and the hardness on the erosion behavior of the dierent heat treated specimens were examined. Finally, SEM images of the samples were deeply analyzed and the erosion mechanisms which occurred on the surfaces of the samples were discussed.
