“…The water temperature directly affects the kinetics constant of the mass transfer process. The corrosion rate of the metal doubles, which is controlled by the charge transfer process with a temperature increase of 10 K or by a diffusion process for a temperature increase of 30 K [13]. The temperature can also change the corrosion of aluminum and the scaling of the platinum grading electrode by affecting the solubility of the reactants and products [14].…”

To optimize the operating temperature and flow velocity of cooling water in a high voltage direct current (HVDC) thyristor valve cooling system, the erosion corrosion characteristics of aluminum electrodes in deionized water at various temperatures were studied. With increasing water temperature, the corrosion current of the aluminum electrode gradually increases and the charge transfer impedance gradually decreases, thus, the corrosion of aluminum tends to become serious. The aluminum electrode in 50 °C deionized water has the most negative corrosion potential (−0.930 V), the maximum corrosion current (1.115 × 10−6 A cm−2) and the minimum charge transfer impedance (8.828 × 10−6 Ω), thus, the aluminum corrosion at this temperature is the most serious. When the temperature of deionized water increases, the thermodynamic activity of the ions and dissolved oxygen in the deionized water increases, and the mass transfer process accelerates. Therefore, the electrochemical corrosion reaction of the aluminum surface will be accelerated. The corrosion products covering the aluminum electrode surface are mainly Al(OH)3. With increasing water temperature, the number of pits and grooves formed by corrosion on the aluminum surface increased. In this paper, the molar activation energy Ea and the equilibrium constant K of the aluminum corrosion reaction with various temperatures are calculated. This clarifies the effect of temperature on the aluminum corrosion reaction, which provides a basis for protecting aluminum from corrosion. The results of this study will contribute to research that is focused on the improvement of production techniques used for HVDC thyristor valve cooling systems.

“…With regards to experimental test methods, Prozhega et al (2014) [5] concluded that an analysis of the data presented in the literature has shown that, from the methodological viewpoint, studies of erosion-corrosion wear in abrasive free media are the most clear. The standards of the American Society for Testing and Materials (ASTM) are widely employed as the method for studying erosion-corrosion wear [8].…”

“…Previous reviews by one of the authors [1,2], describing the mechanisms involved, are still current and recommended to those seeking to gain a general orientation in this area. A more recent review by Prozhega et al (2014) [5] is also recommended. This [3] review will seek to summarise the work that has taken place over the past decade, with the intention of offering an update to the two reviews (by one of the authors) mentioned previously.…”

Erosion-corrosion is attracting increasing attention as a research area, as the increased publication rate attests to. A decade has passed since the last general reviews of the field by one of the authors [1, 2], thus this review is designed to serve as an update to broader reviews published previously. In the past decade, computational fluid dynamics (CFD), semi-empirical and analytical models have been explored, the erosion-corrosion of stainless steels have been thoroughly investigated through testing and the performance of corrosion inhibitors and coatings have been evaluated. Thus, the research that has been conducted can broadly be described as focusing on one of three areas: modelling, testing of material response and protection against material loss due to erosion-corrosion. Although the research conducted in the past 10 years is both meaningful and relevant, it is hoped that greater attention will be given to the advancement of a more fundamental and general theory of erosion-corrosion.

“…Several test geometries have been used for erosion and erosion-corrosion testing, including slurry pot tests and submerged impinging jets (SIJs) [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. SIJs are one of the most commonly used methods for erosion-corrosion testing, being ideal for completing analysis of high velocity flow across a range of temperatures and brine chemistries in sand-laden conditions.…”

Erosion-corrosion degradation in oil and gas pipelines is a significant problem, and a change in flow geometry can significantly enhance rates of degradation. In this study, a 3D printed 90° elbow, integrated into a flow loop, was developed to evaluate erosioncorrosion of X65 carbon steel along both the inner and outer internal portions of the bend in an aqueous carbon dioxide (CO2)-saturated environment containing sand particles.Designing representative geometries capable of measuring rates of corrosion, erosion and their synergistic interactions, can be challenging and currently no designs have been reported in literature that effectively integrate the required measuring techniques to determine local degradation rates throughout the component. To elucidate the individual contributions to overall erosion-corrosion degradation rates, gravimetric and electrochemical measurement techniques were used to quantify degradation rates at multiple locations in the flow geometry, with the specimen design also enabling the possibility of completing acoustic emission measurements to detect particle impacts. The design of the elbow is presented and erosion-corrosion tests were conducted to determine the magnitude and individual contributions of erosion, corrosion and erosioncorrosion interactions at a flow velocity of 6 m/s in a CO2-saturated, pH 4, 60C, 2 wt.% NaCl solution containing 1000 mg/L of sand particles.
