In the present scenario, additives take a superior part in enhancing the performance of thermal barrier coatings. Adding them in small percentages explicitly enhances the lifetime, efficiency, and corrosion resistance of coating materials. In this paper, the influence of additives on the performance of thermal barrier coatings has been discussed extensively. Conclusions from earlier works reveal that the carbon nanotubes (CNTs) have shown good toughness and hardness due to the formation of CNT bridges across the splats. Conversely, Young's modulus decreases with an increased percentages of CNTs. The major drawback with the TiN (titanium nitride) additive is that it will be oxidized at a temperature above 450 °C and the defects in CeO2 (Cerium oxide) are due to the presence of oxygen vacancies under different conditions. However, there is no remarkable research identified on graphene and its oxides, h-BN(Hexagonal boron nitride), TiN, and CeO2-added thermal barrier coatings. [ABSTRACT FROM AUTHOR] |
