The monetary cost of corrosion is currently estimated at 3 to 4% of the global GDP considering direct costs exclusively. However, no study to date has quantified the environmental impact associated with steel corrosion. Here, we determined that the CO emissions associated with the steelmaking required to replace corroded steel will be 4.1-9.1% of the total by 2030 considering the European Union and recent U.S. greenhouse gas reduction targets. We suggest that implementing corrosion management best-practices could drastically reduce the greenhouse gas emissions associated with the replacement of corroded steel and emphasize the need for coordinated international efforts.

The corrosion rates of carbon steel and galvanized steel according to the ISO 9223 standard, the effect of pollutant contamination and atmospheric aggressiveness under high rainfall conditions in the Chocó department were studied. Carbon and galvanized steel samples, chloride, and sulfur collectors were exposed in three atmospheric stations in three strategic positions covering the Colombian Pacific: Quibdó, Andagoya and Bahía Solano, for different exposure periods (up to 18 months). The structural-micro characterization of corrosion products was evaluated via X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy SEM-EDS.

A bimetallic organic framework (CuNi-MOF) was synthesized as a corrosion inhibitor using the solvothermal method. The effectiveness of the inhibitor in corrosion prevention of AISI 304 and 316 in 1N hydrochloric acid solution at room temperature was evaluated using weight loss measurements, electrochemical methods, and surface characterization techniques. The formation of CuNi-MOF protective layer on the stainless-steel surface was confirmed through Field Emission Scanning Electron Microscopes (FESEM), Energy Dispersive Spectroscopy (EDS), and X-Ray Diffraction (XRD) analysis.

Mild steel provides strength to various building and industrial materials but it is badly affected by corrosion. In the present study, we investigate the efficacy of , a plant-based green corrosion inhibitor to minimize mild steel corrosion in a 1 M HSO solution. Weight loss, surface coverage, inhibition efficiency, and corrosion rate measurements were evaluated for various inhibitor concentrations and time intervals.

Biofilms can cause biofouling, water quality deterioration, and transmission of infectious diseases. They are also responsible for microbiologically influenced corrosion (MIC) which can cause leaks, resulting in environmental disasters. A new disposable biofilm/MIC test kit was demonstrated to distinguish abiotic corrosion of carbon steel from MIC.

Based on the bidirectional electromigration (BIEM) technique, a corrosion inhibitor solution was prepared by mixing 1 mol/L triethylene tetramine with deionized water. The effects of current density, charging time, and corrosion inhibitor on critical current density and hydrogen content of rebar were investigated. Subsequently, the hydrogen embrittlement risk of rebar was further characterized by mechanical property tests.
