Rising demand from industries, such as power generation, aerospace, and automotive, is expected to drive the market growth. In the power generation industry, thermal barrier coatings prevent components like turbine blades from overheating, allowing turbines to operate more efficiently at higher temperatures. In the aerospace and automotive industries, thermal barrier coatings help increase the fuel efficiency and performance of engines by allowing engines to operate at higher combustion temperatures. Growing demand for fuel efficient vehicles and need for power generation from clean energy sources is expected to boost the demand for thermal barrier coatings during the forecast period.

Emerging use in new industrial and commercial applications

The use of thermal barrier coatings is expected to significantly grow in new industrial sectors in the coming years. TBCs are increasingly being used in various applications that require components to withstand high temperatures for extended periods of time. With advancements in material science and coating technologies, these protective coatings can now be effectively applied on components used in industries like diesel engines, gas turbines, aluminum casting, etc.

Especially, thermal spray coatings are emerging as a game changer for components used in locations where temperatures frequently exceed 500 degrees Celsius. Their ability to prevent heat transfer and protect substrates from corrosion, oxidation, and thermal fatigue is enabling the broader use of TBCs in the automotive, energy, and manufacturing sectors. For example, in diesel engines TBC coated parts are allowing higher compression ratios and combustion temperatures for better fuel efficiency. Similarly, coatings on blades and vanes of industrial gas turbines are supporting higher operating temperatures for maximized output and efficiency. Even components used in aluminum casting and die-casting are benefiting from protective thermal barrier coatings for improved productivity and quality.

Research is also ongoing to develop next generation coating materials and application techniques to facilitate the use of TBCs in newer industrial processes involving high heat. This includes exploring ceramics, rare earth oxides, and non-line-of-sight coating technologies. The goal is to offer coatings solutions for applications in advanced manufacturing like 3D printing, laser cladding, and heat treatment of special alloys that require localized heat management. Once commercially viable solutions emerge, they can open up whole new domains for thermal barrier coatings beyond traditional usages. This potential for expanding into new industrial segments with evolving needs will be a key driver of future demand.

Stringent emission regulations on combustion systems

Growing concerns about environmental pollution and climate change are prompting governments worldwide to introduce increasingly stringent emission norms for engines and industrial combustion systems. This regulatory pressure is direct forcing the operators of diesel systems, boilers, furnaces, and heat treatment equipment to optimize combustion processes for lower greenhouse gas and toxic emissions. One of the most important strategies adopted towards this end is lifting maximum operating temperatures of systems through effective heat management.

This is where thermal barrier coatings come into play as they help combustion equipment run at higher temperatures without damage to internal parts. The higher ignition and combustion temperatures allowed by TBC coated components result in more complete fuel burn and reduced formation of pollutants.
