“…The second possible reason is that Figure 6 displays the erosion rate of Al x CoCrFeNiTi 0.5 HEA coatings and Cr16 alloy as a function of impingement angle after erosion for 30 min. The Al 1.0 HEA coating and Cr16 alloy showed the maximum erosion rate at 45 • , then the erosion rate decreasing gradually with the impingement angle, which is consistent with the theory of the ductile mode of erosion behavior [19,20]. The erosion rate of the Al 1.5 HEA coating approached a maximum at 60 • and then decreased at 90 • .…”

High-entropy alloys (HEAs) have gained extensive attention due to their excellent properties and the related scientific value in the last decade. In this work, Al x CoCrFeNiTi 0.5 HEA coatings (x: molar ratio, x = 1.0, 1.5, 2.0, and 2.5) were fabricated on Q345 steel substrate by laser-cladding process to develop a practical protection technology for fluid machines. The effect of Al content on their phase evolution, microstructure, and slurry erosion performance of the HEA coatings was studied. The Al x CoCrFeNiTi 0.5 HEA coatings are composed of simple face-centered cubic (FCC), body-centered cubic (BCC) and their mixture phase. Slurry erosion tests were conducted on the HEA coatings with a constant velocity of 10.08 m/s and 16-40 meshs and particles at impingement angles of 15, 30, 45, 60 and 90 degrees. The effect of three parameters, namely impingement angle, sand concentration and erosion time, on the slurry erosion behavior of Al x CoCrFeNiTi 0.5 HEA coatings was investigated. Experimental results show AlCoCrFeNiTi 0.5 HEA coating follows a ductile erosion mode and a mixed mode (neither ductile nor brittle) for Al 1.5 CoCrFeNiTi 0.5 HEA coating, while Al 2.0 CoCrFeNiTi 0.5 and Al 2.5 CoCrFeNiTi 0.5 HEA coatings mainly exhibit brittle erosion mode. AlCoCrFeNiTi 0.5 HEA coating has good erosion resistance at all investigated impingement angles due to its high hardness, good plasticity, and low stacking fault energy (SFE).

“…Several studies have focused so far on developing FE models for simulating the erosion caused by solid particle impact of ductile metals such as AISI 4140 steel and nickel (Ni), Al6061-T6, Ti-6Al-4V and britle ceramics such as tungsten carbide (WC), Cr3C2, and SiC [50][51][52][53]. The models developed enabled an in-depth study of the stresses and strains produced during the erosion process and also assess the efect of testing factors such as particle size, shape, velocity, and impact angle on the erosion rate.…”

Material removal caused by the impact and sliding of a stream of particles is a typical wear mode in the oil and gas industry. Protective coatings can be employed to increase the service life of equipment that is exposed to harsh erosive and abrasive environments. Among all the types of protective coatings and liners, polyurethane elastomers have received great atention owing to their excellent wear resistance and comparatively low cost that would allow for large-scale applications. The excellent wear resistance of polyurethane elastomers is a result of their high resilience and propensity to elastic deformation that enables the absorption of impact energy of erodant particles with minimal damage. The relation between the wear resistance of polyurethane and its mechanical properties has been the subject of previous studies. This chapter reviews the research that has been conducted to study the wear resistance of polyurethane elastomers. Testing apparatuses employed, material characterization techniques, evaluations of material removal mechanisms, and parameters with the strongest efect on wear resistance of polyurethane elastomers are herein explored. A review of inite element modelling approaches for in-depth study of the wear phenomenon of polyurethane elastomers is also presented in this chapter.

“…Several attempts have been made to understand the effect of different parameters, such as; temperature, particles size, and microstructure of both the impinging and eroding surfaces on the solid particles erosion process [11][12][13][14][15][16][17]. However, each parameter behaves in a manner peculiar to each process and is often complex due to interrelated variables involved [18][19][20][21][22][23][24]. Among these parameters, particle velocity and impact angle play critical roles in the erosion process [25][26][27][28].…”

“…Ductile materials belong to the group that plastically deformed with a maximum erosion rate at low impact angles, while brittle materials fracture with a maximum erosion rate at normal impact angles. Despite several studies on the effects of impact angle and speed on the solid particle erosion of these groups of materials [19,23,[38][39][40], efforts are still required to understand the erosion mechanism of API X100 steel by solid particles as this material is widely used in the petroleum industry. Further study on the effect of particle speed on the erosion of API X100 steel at 30 • and 90 • impact angles becomes necessary.…”

Abstract:Erosion is the gradual removal of material due to solid particle impingement and results in a failure of pipeline materials. In this study, a series of erosion tests were carried out to investigate the influence of particle speed and impact angle on the erosion mechanism of API X100 pipeline steel. A dry erosion machine was used as the test equipment, while the particle speed ranged from 20 to 80 m/s and impact angles of 30 • and 90 • were used as test parameters. The eroded API X100 steel surface was characterized using scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS). The weight loss and erosion rate were also investigated. The results showed that at a 90 • impact angle, a ploughing mechanism was occurring on the tested specimens, while material removal through low-angle cutting was the dominant mechanism at lower impact angles. Embedment of alumina particles on the target steel surface, micro-cutting, and low-angle cutting were observed at low impact angles. Therefore, the scratches, cuttings, and severe ploughings observed on some failed oil and gas pipelines could be attributed to the erosion mechanism.
