Erosion–Corrosion in Single‐ and Multiphase Flow

Comparison of erosion, corrosion and erosion–corrosion of carbon steel in fluid containing micro- and nanosize particles

“…The presence of nanoparticles causes an increase in kinematic viscosity, 24 and as a consequence, the surface shear stress also increases accordingly. 36 It is also possible that the collision energy of nanoparticles has been adequate to break up and peel the oxide pieces from the surface. Both of these factors can contribute to increase the surface erosion by peeling the oxide layers.…”

“…Owing to the greater material loss than the sum of individual components, the interaction between chemical (or electrochemical) and mechanical damages is referred to as 'synergistic' and/or 'additive' effects. [33][34][35][36][37][38] Published results on the erosion-corrosion of fluids containing large particles indicate that the reductions in mass and thickness due this phenomenon can lead to a substantial reduction in the life of industrial equipment and structures. For example, the mass reduction rates in pipeline samples made of steel X65 (API-5L-X65) in a solution containing 100 and 500 ppm SiO 2 particles with sizes ranging between 106 and 425 mm, within 2 h of experiment, have been ,32 and 45 mg respectively.…”

Effects of cylinder head temperature and coolant velocity on the erosion behavior of water jacket in a diesel engine

“…Surface defects in the form of small protrusions or depressions such as pits can give rise to disturbed flow on a smaller scale, but are sufficient to initiate erosion-corrosion. In addition, bubbles and detached part of the specimen in the coolant are also sources of mechanical impacts on the specimen surface [28]. The surface components of the specimens were detected using energy dispersive X-ray spectroscopy (EDS).…”

“…In contrast, the effect of cavitation on the erosion can be excluded because the coolant velocity is not sufficiently high to 8 induce cavitation phenomena in automotive engines. However, the coolant velocity should be considered because the mechanical impact due to coolant velocity is an important source of the erosion [27,28].…”

An Erosion-Corrosion Investigation of Coated Steel for Applications in the Oil and Gas Field, Based on Bipolar Electrochemistry

“…Erosion-corrosion processes involve complex mechanical and electrochemical mechanisms whose combined action often results in a significant increase in material degradation [1,[16][17][18]. The degradation mechanism is affected by factors controlling both corrosion and erosion.…”
