The circular saw blade, which is mainly composed of carbon steel, is used to cut the stone. However, the carbon steel is easily corroded in stone processing wastewater, shortening its lifespan. In this study, a new composite inhibitor of sodium nitrite, sodium molybdate, sodium silicate, sodium tungstate, and sodium citrate was investigated firstly, and then, its inhibition efficiency for carbon steel in stone processing wastewater was explored using electrochemical measurements and weight loss measurements. The results showed that the composite inhibitor as a mixed‐type inhibitor displayed good inhibitory performance. Surface analysis including scanning electron microscope, atomic force microscope, X‐ray photoelectron spectroscopy analysis, and contact angle test further revealed the form of protection of the steel surface by composite corrosion inhibitors. The prepared composite inhibitor exhibited excellent corrosion resistance for carbon steel in stone processing wastewater, and it is believed that the composite inhibitor has certain application potential in industries.

“…The synergistic effects of organic/inorganic CIs showed a potent corrosion inhibition power of 96%. Li and coworkers combined CLE with different inorganic cations (Ca 2+ , Fe 3+ , Fe 2+ , and Ni 2+ ) to enhance the corrosion resistance of Mg alloy AZ91D [52]. The CLE-Ca 2+ -based inhibitors exhibited the slightest corrosion, and the IE was 92%.…”

Metal materials are vulnerable to corrosion in the process of production and service, which often leads to serious disasters, including the decline of the performance of metal components and the shortened service life, and even causes catastrophic accidents and ecological damage. Adding a certain amount of corrosion inhibitors (CIs) to the corrosive medium is a simple, efficient, and economical anti-corrosion method to slow down and restrain the corrosion of metal materials. Organic corrosion inhibitors (OCIs) are considered to have good application prospects and are widely used for surface anti-corrosion of metal materials, as they generally have advantages such as good metal adsorption, low oxidation resistance, good thermal and chemical stability, and green environmental protection. This paper systematically summarized some major OCIs, including alkyl chains, imidazoles, and pyridines, and their structural characteristics, as well as the action mechanism of OCIs. Moreover, this paper discusses some natural compounds used as environmentally friendly CIs and provides a prospect for the development trend of OCIs.
