Erosion corrosion is a combination of actions. Corrosion results in an oxide on a metal’s surface. The oxide, though, slows the attack because it prevents fresh corrodent from reaching the surface. If there’s a fast fluid flow that scrubs the oxide off the surface, corrosion continues at a very rapid rate.The present study compares corrosion behaviour of three austenitic stainless steels 316L, 317L and 904L (base materials and welds) in wet-process phosphoric acid (WPA) and reagent grade phosphoricThe phosphoric acid industry: Equipment, materials, and corrosion

The corrosion rate obtained using gravimetric and electrochemical tests was 7.8 μm/year and 5.7 μm/year, respectively. According to the results obtained in this research, EIS techniques could be a feasible option to control corrosion in CSP plants and reduce operational risks during the molten salt thermal-electricity conversion.The current stage of development of promising gas and gas-condensate fields on the territory of Russia is realized at the extracting plants whose products contain carbon dioxide (CO 2).The presence of carbon dioxide, in combination with moisture and other factors, stimulates the intense development of corrosion processes and requires Corrosion Activity of Operating Conditions for the Steel

The extraction of corrosion inhibitors from plants is in line with the concept of green chemistry. Plant extract corrosion inhibitors can reduce the harm inflicted on the human body and environment, which Flow-accelerated corrosion (FAC) is the main degradation mechanism of the steam/water circuit in carbon steel from nuclear, fossil, and gas power plants. This general type of corrosion can lead to the rupture of piping and has, in a few dramatic cases, lead to casualties. Key parameters influencing FAC are pipe isometrics, alloy contentFlow-accelerated corrosion in nuclear power plants

Biological corrosion at sewage treatment plants is caused by corrosive secretions (metabolic products) of microorganisms. The conditions prevailing there are very good for rapid development of bacteria. Treatment plants are hardly ever completely filled with sewage and as a result there is a lot of space above the water line for bacterialIntroduction. Corrosion is the destructive attack of a material by reaction with its environment [] and a natural potential hazard associated with oil and gas production and transportation facilities [].Almost any aqueous environment can promote corrosion, which occurs under numerous complex conditions in oil and gas production, processing, Corrosion problems during oil and gas production and its
