“…13 Average corrosion rate (based on weight loss) vs particle velocity for API X42 steel during erosion-corrosion test in which each data point is an average of five corrosion cycles corrosion on erosion and vice versa is significant. For 36,47,63, and 81 m s -1 particle velocity, the increase in erosion rate due to corrosion is around 55, 15, 35, and 34 %, respectively. On the other hand, there are around 2, 3, 4, and 5 times increase in corrosion rate due to erosion for 36, 47, 63, and 81 m s -1 particle velocity, respectively.…”

“…During pure erosion, API X42 steel was exposed to abrasive stream for 50 s at 90°angle of incidence and different particle velocities (36,47,63, and 81 m s -1 ). Erosion rate in the absence of corrosion (E 0 ) was calculated using Eq.…”

Hydro-transportation is an economic and flexible way to transport natural resources such as oil and gas from excavation to the extraction plants, refineries, and consumer-ready products to markets. However, interaction between solid particles, corrosive fluid, and target material often results in significant mutual reinforcement due to the combined action of erosion and corrosion. In this study, erosion-corrosion behavior of API pipeline steel has been assessed in 2 g l -1 NaCl solution purged with CO 2 as the corrosive media and aluminum oxide as the erodent. Four different particle velocities (36, 47, 63, and 81 m s -1 ) were employed, while the angle of incidence was kept constant at 90°. The synergism between erosion and corrosion has been studied by means of a newly designed test approach to mitigate the limitations of the in situ method and to identify the effect of erosion on corrosion and vice versa. The corrosion process was monitored using potentiodynamic polarization and weight loss measurements. Total material loss rate and the components of erosion, corrosion, and their synergistic interactions have been determined. Scanning electron microscopy examination and experimental results show that there is an immense correlation between erosion and corrosion. Significant synergism was observed due to the interaction of different erosion and corrosion mechanisms.

“…SEM images in Figs. 6(a) and 6(b) do not provide strong evidence that the degree of erosion is greater in the CS1 than in the case of the CS2 alloy; however, the presence of a high volume fraction of ledeburitic carbides in the CS2 alloy may detrimentally affect the material erosion resistance at high impingement angles [10]. Similar to the CS2 eroded surface, the eroded surfaces of the CS3, CS4, and CS5 alloys exhibit faceted-type fracture characteristics (Figs.…”

The erosive-wear response of five commercial ferrous-based cast alloys used for crushing was examined in this study. The microstructures of the alloys were modified to elucidate the effect of microstructural features on wear. Erosion tests were conducted using aluminum oxide particles (90-125 µm) at 70 m/s and a normal impact angle (90°). The worn surfaces were characterized by scanning electron microscopy and 3D non-contact laser profilometry. It is found that (i) a pearlitic structure exhibiting a greater plastic deformation than both bainitic and martensitic structures shows the greatest resistance to erosive wear at normal impact and (ii) the fracture characteristics of carbide and graphite particles plays an important role in determining the erosion wear behavior of the cast alloy matrices.

The present work is devoted to the study of the solid particle erosion resistance of steels 20kH13 and 15kH11MF applied for manufacturing of the first stages stationary and rotating blades of high and medium pressure cylinders of steam turbines.The paper describes the experimental rig for the solid particle erosion resistance investigation of structural materials and protective coatings as well as the research's method of varying experimental parameters influence (air-abrasive flow rate and solid particles angle of attack) on the dynamics of the blade steels (20kH13 and 15kH11MF) solid particle erosion process.It has been established that the surface injury (destruction) of the blade steel 20kH13 and 15kH11MF samples rises during the solid particle erosion process with increasing of air-abrasive flow rate and reaches its maximum value at attack angles close to 30°.
