“…According to the dependence of energy loss to incident angle highlighted in the previous section, the wear volume is expected to be strongly dependent on incidence angle. This dependence on incidence angle has also been experimentally observed previously [41,46]. Horizontal error bars display the dispersion of the controlled incidence angle and correspond to the 20 th and the 80 th percentiles.…”

Wear generated by repetitive impacts between an Inconel tube sample and a stainless steel flat bar target is studied through experiments in dry environment. Incident energy and angle of impacts are controlled, normal and tangential loads during impact are measured as well as rebound energy and angle of impacts. Impacts characteristics are analyzed and the influence of the energy loss during impacts and the incidence angle on generated wear is analyzed. Wear volume is found to be proportional to the energy loss, for which a maximum is observed at an incidence angle close to 25° from horizontal. An impact wear energy coefficient is introduced and an impact wear law with a strong mechanical meaning is proposed. This energy-based law well predicts the observed experimental wear. Highlights Impact wear between an Inconel tube and a stainless steel bar is studied. Wear is observed to be proportional to the energy loss during impacts. The energy loss during impacts strongly depends on incidence angle. An energy-based impact wear law is proposed.

“…Different techniques were used to identify the zones of maximum localized wear and ways to minimize it. Messaadi et al [ 53 ] performed their work both experimentally and numerically. It has been shown that the interacting angles and quantity of friction played a pertinent role in surface failure.…”

Centrifugal pumps are being widely used in various industries for moving fluids that carry solids through pipelines where the need of head and flow rate is not high. Slurry erosion and cavitation are an extremely complex and not yet fully understood phenomenon that occur in centrifugal pumps; however, these undesirable phenomena can be reduced to a certain extent. Appropriate design and development of experiments is required to reasonably predict slurry erosion and cavitation. However, CFD methodology complements analytical solutions and experiments whenever testing of equipment has limitations. The current paper highlights the various slurry erosion and cavitation reduction techniques utilized by different researchers. Economic analysis conducted for a case study relevant to centrifugal pump (CP) usage in Pakistan shows that an 8% enhancement in pump efficiency can reduce the life cycle cost to about 17.6%, which could save up to USD 4281 for a single pump annually in Pakistan.

“…In order to study the movement of impact-sliding, several test devices have been developed. [9][10][11][12][13][14][15] Messaadi et al 16,17 studied the impactsliding wear of sintered steel and determined that the impact angle, temperature, friction coefficient, and lubrication conditions had significant impacts on the wear behavior of impact-sliding. The impact angle was closely related to the interfacial shear stress and the main damage was transformed from shear deformation to plastic deformation and delamination with the increase in the impact angle.…”

Kermouche et al 19 modeled the impact-sliding process using a scratching process of a double-layered material (stainless steel covered by a friction film) with a rigid spherical asperity and determined the importance of plastic yielding in impact-sliding wear.…”

Impact-sliding wear is a typical form of composite wear and occurs in many industrial equipment. The effects of structural stiffness on the impact-sliding wear damage and mechanisms of aluminum alloy were investigated using a bespoke impact-sliding device. The damage evolution and mechanisms of the impact-sliding wear for three different structural stiffness conditions were analyzed. Results showed that the main damage zone gradually shifted along the sliding direction with the increase in the structural stiffness. The wear damage of the material was higher for the low and high structural stiffness conditions and resulted in a very rough surface. However, for the medium structural stiffness, the impact-sliding wear exhibited a slow and linear increase and relatively smooth wear scars were observed. Moreover, the main wear mechanism transformed from delamination to ploughing as the structural stiffness increased.
