“…[35] The uniform corrosion sub-type is defined as general corrosion where the metal degrading is not in contact with other metals of different corrosion potential or the corrosion mechanism itself is not enhanced by microbial activity. [36] If these latter phenomena are active, general corrosion is then defined as either galvanic corrosion or microbiologically induced corrosion respectively. Galvanic corrosion occurs when two dissimilar metals are in contact in aqueous environment.…”

Geothermal power plants are complex systems, where the interplay between different metallic components transforms the enthalpy of hot brine in the form of electricity or usable heated water. The naturally occurring variety in brine chemistry, linked to the presence of specific key species, and its thermo‐physical properties, leads to the development of different power plant configurations. Key species and power plant configuration in turn determine the extent of damage experienced by each component in the power plant: erosion, corrosion, and/or scaling, often acting combined. Paints and coatings, compared to changing the component alloy, have represented a preferred solution to mitigate these issues due to advantages in terms of costs and repairability. This is reflected in the large number of publications on research and development in this area within the past ≈50 years, with even an increasing trend in the past 10–20 years, indicating the strong interest to develop this clean and sustainable energy source. Therefore, in this work, the first of its kind after 1980, an in‐depth review of all published work on research performed on paints and coatings for geothermal applications, subdivided by the material system, is provided.

“…Furthermore, the obtained values are close to those reported for the same materials in acidic chloride solutions of similar concentrations. [52][53][54] Cyclic polarization (CPP) is used to determine the susceptibility of the studied materials to the localized pitting corrosion. [55] Analysis of the polarization curves in Figure 2 reveals different behaviors of the examined materials with regard to the localized corrosion.…”

Recently, an emerging electrodeposition-redox replacement (EDRR) method was demonstrated to provide exceptionally efficient gold recovery from cyanide-free hydrometallurgical solutions. However, the effect of electrode material and its corrosion resistance in this process was overlooked, even though the EDRR process is carried out in extremely corrosive, acidic chloride solution that also contains significant amounts of strong oxidants, i.e., cupric ions. In the current study, nickel alloy C-2000, stainless steels 316L and 654SMO, and grade 2 titanium were for the first time critically evaluated as potential cathode materials for EDRR. The particular emphasis was placed on better understanding of the effect of cathode substrate on the overall efficiency of the gold recovery process. The use of a multiple attribute decision-making method of material selection allowed reaching of a well-founded compromise between the corrosion properties of the electrodes and process efficiency of gold extraction. The 654SMO steel demonstrated outstanding performance among the examined materials, as it enabled gold recovery of 28.1 pct after 3000 EDRR cycles, while its corrosion rate (CR) was only 0.02 mm/year.

“…An ongoing challenge in the oil, gas and geothermal industries is the design of materials for casings, pipes and other installations that resist corrosion (Abadeh and Javidi, 2019;Faes et al, 2019;Ibrahim et al, 2018;Miranda-Herrera et al, 2010;NAM, 2015;Provoost et al, 2018;Veldkamp et al, 2016). Currently, carbon steel is the most widely used engineering material because the material is strong, easily available and relatively cheap (Batis et al, 1997;Odusote et al, 2012;Provoost et al, 2018;Reinecker et al, 2019;Wang, 2018).…”
