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.

Key Takeaways from Analyst:

The thermal barrier coatings market is expected to experience steady growth in the coming years. The market is driven by the increasing application of thermal barrier coatings in industries such as aerospace, industrial gas turbines, and automotive. Thermal barrier coatings provide protection to parts in high temperature applications by reducing heat transfer. This improves component life and performance.

Thermal barrier coatings find major use in aircraft engines and parts to sustain extreme operating temperatures. Rising application of gas turbines for power generation is another driver as thermal protective coatings help increase the turbine efficiency.

Stringent environmental regulations pose a challenge. The manufacturing process of some thermal barrier coatings produces hazardous waste which requires safe disposal. High material and production costs could also limit adoption in price sensitive applications.

Opportunities lie in developing advanced coating materials with longer lifespan and higher temperature resistance. This would improve process efficiency. Growth of the automotive industry particularly in Asia Pacific presents an avenue as turbocharged vehicles increase the demand for heat resistant components. Rising MRO activities in aviation also ensures aftermarket opportunities.

Market Challenges: High procurement cost

The high procurement cost associated with thermal barrier coatings is significantly restraining the growth of the global market. Thermal barrier coatings are specifically engineered material systems used to provide thermal insulation as well as protect expensive metal alloy components that operate at high temperatures, from melting or corroding. However, developing and producing these specialized coating materials and application processes requires extensive research and developmental investments. The coating materials often involve complex synthesized ceramic compounds or mixed metal alloys which are expensive to produce. Further, the application of these coatings requires specialized thermal spray or physical/chemical vapor deposition equipment which have high set up and recurring costs.

Market Opportunities: Development of next generation coatings

The development of next generation coatings is posing a significant restraint to the growth of the global thermal barrier coatings market. Thermal barrier coatings have been traditionally used in high-temperature applications such as turbines, engines and furnaces to provide insulation to underlying components and increase their operational life. However, continuous research and development towards alternative insulation solutions has started yielding new coating technologies that provide better heat resistance compared to traditional thermal barrier coatings.

Insights by product type: Thermal compatibility drives growth in the ceramics segment

In terms of product type, ceramics is expected to contribute 36.2% share of the market in 2024, owing to its ability to withstand high thermal stresses and compatibility with a wide range of substrate materials. Ceramic coatings exhibit higher thermal expansion coefficient matching with metal alloys used in gas turbine components like blades and nozzles. This thermal compatibility allows ceramics to effectively insulate the underlying superalloys from extreme combustion temperatures in jet engines and power plants. Ceramic coatings like zirconia partially stabilized with yttria (YSZ) and alumina (Al2O3) possess high resistance to sintering and creep at elevated temperatures making them suitable for applications with continuous firing at 800°C or above. Their inertness to corrosion and oxidation in hostile environments further reinforces the use of ceramics as durable thermal barrier coatings.

Insights by coating materials: AL2O3 retains its edge due to proven performance record

In terms of coating materials, AL2O3 is expected to contribute 40.3% share of the market in 2024, owing to its well-established performance history. Alumina ceramics demonstrate high hardness, chemical stability, and mechanical strength at high operating temperatures. Continuous research over the last few decades have improved deposition techniques and bond coating designs to overcome the shortcomings of thermal fatigue in early AL2O3 coatings. Today, modifications like addition of dopants and multifunctional layered designs have enhanced the cyclic spallation resistance of AL2O3, allowing it to serve for over 50,000 hours in gas turbine combustors without losing integrity. The wealth of performance data on AL2O3 helps aero-engine manufacturers to confidently specify it for new engine development programs. Its simple processing also makes AL2O3 more economical relative to newer coatings, further galvanizing its popularity among commercial suppliers.

Insights by technology: HVOF excels in deposition control and adherence

In terms of technology, HVOF is expected to contribute 35.6% share of the market in 2024, owing to its unique advantage of depositing coatings with controlled microstructure and strong mechanical interlocking with the substrate. The HVOF process involves a high velocity oxygen-fuel thermal spray, where fuel and oxygen are ignited to produce a supersonic combustion gas jet capable of accelerating powder particles to very high velocities. On impact, these particles deform plastically to embed themselves firmly onto the part being coated. This deposition mechanism results in dense coatings with low oxide content and residual stresses. It allows manipulating the coating structure to achieve lower porosity and higher hardness compared to alternative methods like plasma spraying. HVOF techniques also codeposit bond coat materials with the top coat ceramics, promoting a graded interface less prone to delamination. Thermal fatigue experiments have demonstrated that parts coated by HVOF last 3-5 times longer than those treated with other spraying technologies.
