“…By comparing the macroscopic morphology of the corrosion film in Figure 4 , it can be seen that with the increase of temperature, the densification of the corrosion product film on the sample surface deteriorates. Seo et al found that when the corrosion solution contains chloride ions, the copper ions in the substrate react with Cl − in polarization, forming porous corrosion films [ 23 ]. When the temperature increases, the ionic activity in the solution increases, and the corrosive medium easily enters the substrate through the damaged point of the corrosion film, accelerating the formation of pitting corrosion.…”

The System #2 flow loop used in this study is a 4−inch−diameter, high−temperature, high−pressure system. In situ corrosion and electrochemical measurements were performed using a homemade flat corrosion specimen and a three−electrode probe. The experiment results show that temperature has an accelerated influence on the corrosion of antibacterial alloy steel. With the increase of temperature and the presence of O2 in the environment, a loose and porous corrosion product film was formed on the surface of the resistant steel, which made it easier for the corrosion medium to enter the corrosion product film from the pore, thus accelerating the corrosion.

“…Carbon steel is a common type of steel widely used in circulating cooling water systems [1]. Due to perennial exposure to water, this steel's corrosion resistance is easily compromised [2], and annual losses caused by corrosion account for 2-4% of countries' GDP (Gross Domestic Product) [3], surpassing the combined losses caused by fires, winds, and earthquakes. The presence of Cl − and SO 4 2− in recirculating cooling water environments induces pitting on carbon steel [4] and can penetrate the passive layers of the metal [5], further compromising its corrosion resistance in circulating cooling water environments.…”

Developing environmentally friendly and biodegradable corrosion inhibitors is an important research direction due to the toxicity and non-degradability of conventional carbon steel corrosion inhibitors added to circulating cooling water environments. Polysaccharides in EPSs (Exopolysaccharides) can be used as green corrosion inhibitors, but a low inhibition rate limits their practical application. Chemical modification is widely used to modify the functionality of polysaccharides by altering their physicochemical properties and structures, thereby enhancing or supplementing their functional characteristics. In this study, we employed chloroacetic acid as an esterifying agent to chemically modify Dextran and successfully synthesized a modified polysaccharide derivative with a substitution degree of 0.326. This derivative efficiently inhibited the corrosion of carbon steel in circulating cooling water environments. The carboxymethylated dextran (CM-Dextran) formed after synthesis could adsorb onto metal surfaces to form a protective film, thereby inhibiting metal surface dissolution reactions and exhibiting anodic corrosion inhibition properties. The experimental results showed that the corrosion inhibition efficiency of CM-Dextran after modification increased by up to 57.4%, with a maximum inhibition efficiency of 82.52% at a concentration of 4 mg/mL. This study provides new insights and opportunities for the development of environmentally friendly corrosion inhibitors derived from polysaccharides.
