Thermal barrier coatings (TBCs) are thin, ceramic coatings that are applied to metal surfaces to protect them from high temperatures. They work by creating a layer of insulation between the metal and the hot environment. This prevents the metal from absorbing heat, which can lead to thermal fatigue, oxidation, and corrosion.

TBCs are used in a variety of applications where high temperatures are present, such as:

• Aerospace: TBCs are used on the hot parts of aircraft engines, such as the turbine blades and vanes. This helps to improve the efficiency of the engine and extend its lifespan.

• Power generation: TBCs are used on the hot parts of gas turbines, such as the combustor liners and heat exchangers. This helps to improve the efficiency of the power plant and reduce emissions.

• Industrial: TBCs are used on the hot parts of industrial equipment, such as the boilers and furnace tubes. This helps to improve the efficiency of the equipment and extend its lifespan.

According to Stratview Research, the thermal barrier coatings market is expected to grow at a CAGR of 6.4% from 2020 to 2025. The growth of the market is being driven by the increasing demand for TBCs in the aerospace, power generation, and industrial sectors.
