Corrosion Inhibitors Market Size
At a compound annual growth rate (CAGR) of 20.00%, the corrosion inhibitors market is expected to reach US$ 47.4 billion by 2034 from its 2024 valuation of US$ 9 billion.
Chemical products known as corrosion inhibitors are added to water or other process fluids to slow down the pace of corrosion. Corrosion affects the metals and pipelines used in water treatment. Corrosion inhibitors prevent corrosion in metal, oil, gas refineries, and other areas. Substances that suppress corrosion include tungstate, chromate, molybdates, and nitrates. Inhibitors of corrosion slow down the cathodic reaction to prevent reducing species from diffusing too widely across metal surfaces. Inhibitors include things like cathodic poison and oxygen scavengers. The first line of defense against corrosion is a corrosion inhibitor. Various kinds of corrosion inhibitors, such as cathodic inhibitors, limit the migration of reducing species to metal surfaces by slowing down the cathodic process. Anodic inhibitors create a shielding oxide layer on the metal's surface. Significant anodic shifts by anodic inhibitors push the metallic surface into the passivation zone. Anodic inhibitors lower a material's risk of corrosion. Anodic inhibitors include compounds like molybdates, tungstate, nitrates, and chromates. Volatile Corrosion Inhibitors, or VCIs, are volatilized from the source and transferred in a confined environment to the corrosion site.
To stop condenser tube corrosion, volatile chemicals such as morpholine or hydrazine are delivered with steam in boilers—film-forming substances known as mixed inhibitors aid in suppressing both cathodic and anodic processes. Phosphates and silicates are the most widely utilized combined inhibitors in home water softeners to stop rust water development. Every kind of equipment needs to be protected from corrosion. The range of corrosion inhibitors includes applications in various industries, including metal processing, chemical processing, power generation, paper and pulp, water treatment, and oil and gas extraction. Anodic and cathodic corrosion inhibitors provide better protection and enable lower inhibitor concentrations. Organic compounds function as adsorption protective film inhibitors. This inhibitor's surfactant molecular structure includes a hydrophilic group that can interact with the hydrophobic portion of the molecule and the metal surface of most of the solution. Adsorbed inhibitor molecules contribute to slowing down the pace of corrosion by preventing water from penetrating the metal surface and reducing oxygen diffusion. In corrosion protection, environmentally benign corrosion inhibitors in coatings are expanding. There are new chemical and inorganic inhibitors that could potentially replace hexavalent chromium. However, broad applicability has spurred the expansion of the target market.
