Corrosion is a major problem in many industries, causing economic losses and safety and environmental issues. Traditional methods fall short of modern demands, so innovative solutions are vital. Hybrid nanomaterials are promising for corrosion prevention due to their unique properties. This chapter explores their use, mechanisms, and impact. It starts with corrosion's widespread impact and traditional limitations, introducing hybrid nanomaterials. The chapter covers their classifications, fabrication techniques, and properties, including organic-inorganic, inorganic-inorganic, and composite hybrids. It discusses their corrosion inhibition mechanisms and their incorporation into coatings and materials. Real-world applications in aerospace, automotive, oil and gas, and marine industries are highlighted with case studies. Environmental concerns, toxicity, and economic viability are addressed.
