Abstract
This research explores the use of Al2O3, CuO, and Cr2O3 nanoparticles in protective coatings to enhance
durability, corrosion resistance, and thermal stability. The study investigates nanoparticle synthesis, paint
formulation, application methods, and performance testing. Results indicate significant improvements in
hardness, heat resistance, and adhesion strength, making the coatings ideal for industrial, automotive, and
high-temperature applications.
