Nanostructured TBCs offer numerous benefits: - Enhanced Thermal Insulation: The reduced grain size in nanostructured materials decreases thermal conductivity, providing superior insulation. - Increased Durability: Nanostructured coatings have better resistance to thermal cycling, which reduces the risk of cracking and delamination. - Improved Mechanical Properties: The nanostructuring process enhances the toughness and flexibility of the coatings, making them more resilient to mechanical stresses. - Better Corrosion Resistance: The fine nanostructures help in creating dense coatings that are less permeable to corrosive agents.
