“…Temperature is the next factor that affects the intensity of erosive wear. With increasing temperature the material ductility increases that results a change of degradation mechanism and an increase in erosion rate [57][58][59][60]65]. However, an influence of temperature is not as simple as it was mentioned above.…”

“…In addition, even at elevated temperatures, alumina ceramic showed brittle mechanism of erosion. Sarlin et al [60] investigated glass fibre reinforced vinylester composites (VE-FRP) at elevated temperature. Studies carried out at an impact velocity of 4.8 /s, solids concentration (quartz) of 15 wt% and an exposure time of 72 h showed a greater number of vapor cavities at a temperature of 95°C than 80°C.…”

The degradation of materials due to slurry erosion is the serious problem which occurs in the power industries. The paper presents actual knowledge about an influence of individual factors connected with flow conditions, particles and material properties on the slurry erosion resistance. Among the factors connected with operating conditions, an influence of impact angle, and velocity of impact, particle concertation and liquid temperature have been described. In case of the factors connected with solid particle properties, an influence of the size, shape and hardness have been discussed. In the part devoted to the impact of material properties, due to different types of materials, the issues of resistance to erosion of slurries related to the properties of steel, ceramics and polymers are discussed separately. In the paper has been shown that a change of any of mentioned factors causes a change in the erosion rate due to the synergistic effects that accompany to slurry degradation.

“…The higher erosive wear rate may be attributed to the harsh contact between the erodent particles and the composite surface because of the increased kinetic energy of the erodent particles at higher impact velocities. These findings are in good agreement with the previously reported results .…”

Fabrication of waste bagasse fiber‐reinforced epoxy composites: Study of physical, mechanical, and erosion properties

et al. 2019

The aim of the research work is to study the physical, mechanical, and erosive wear properties of sugarcane bagasse fiber-reinforced epoxy composites. The physical (density, void content) and the mechanical (hardness, tensile strength, impact energy, flexural strength) properties of the composites were found to increase with the content of bagasse fiber. For erosive wear analysis, the experiments were carried out with the help of erosion test machine. To minimize the erosive wear rate, Taguchi technique is executed to explore the influence of five control factors including fiber content, impact velocity, impingement, stand-off distance, and erodent size at three levels. Using Taguchi (L 27 ) orthogonal array, the optimal combination of control factors, which yielded minimum erosive wear rate, was statistically predicted and experimentally verified. The fiber content and impact velocity were the two most contributing control factors for the minimization of erosive wear rate. The important sequence of the parameters is fiber content > impact velocity > impingement angle > erodent size > stand-off distance. The optimal combination of control factors was obtained at 10 wt% of fiber content, 30 m/s of impact velocity, 30 of impingement angle, 85 mm of stand-off distance, and 250 μm of erodent size. Finally, composites worn surfaces were examined with scanning electron microscope to study the possible erosive wear mechanism. POLYM. COMPOS., 40:3777-3786, 2019.

“…Then a part of the energy supplied by the electric motor to the system was transferred to the gaseous phase and, consequently, less energy was available for solid particles to cause erosion damage. Some confirmation of the presence of a gaseous phase in tests at 95°C was obtained as the surfaces of FRP materials [32] tested with the same device showed circular holes that resembled cavitation damage when tested at 95°C, which gave an indication of the presence of a gaseous phase.…”
