Selection of Inhibitor and Recent Advances in Enhancing Corrosion Prevention

Corrosion inhibitors are substances that protect metal surfaces by forming a protective film to prevent metallic materials in contact with corrosive environments. Inhibitors are created with capability to adsorb onto the metal surface, creating a barrier film, or neutralizing the detrimental effects of corrosive substances. Their performance are evaluated based on the ability in reducing corrosion rate. Traditionally, corrosion inhibitors made of chemical synthetic compounds. But as synthetic inhibitors have environmental impact, researchers are starting to explore compound alternatives. Currently, inhibitor technologies have demonstrated a remarkable growth in performance marked by the discovery of new types of inhibitors. Ongoing research are focusing on self-healing inhibitor, eco-friendly inhibitor, and nanostructured compounds inhibitors. This paper will comprehensively address the current challenges of advanced corrosion inhibitors. From the investigation, it has been noticed that application of innovative technologies has led to a transformative impact in producing with significant enhancement in their overall performance capabilities.
