Thermal Barrier Coatings Industry Overview
The global thermal barrier coatings market size is expected to reach USD 21.69 billion by 2028, growing at a CAGR of 4.8% over the forecast period, according to a new study by Grand View Research, Inc. Increasing demand for advanced heat resistant coatings from several end-use industries including energy, automotive, and aerospace is expected to have a positive impact on the market growth in the coming years. The growing scope of applications in gas turbines, which are widely used across the energy sector, is also expected to propel the product demand.
The Electron-Beam Physical Vapor Deposition (EBPVD) technology segment is estimated to witness significant growth over the forecast period. EBPVD thermal barrier coatings are widely used for gas turbine engine components to improve engine durability and efficiency. The growing gas turbine market is anticipated to significantly drive the demand for EBPVD thermal barrier coatings over the forecast period.
Rising power generation activities across the globe owing to the growing demand for electricity as a result of population growth and rapid urbanization is boosting the growth of gas turbines for power generation. Gas turbines play an important role in reducing Greenhouse Gas (GHG) emissions. As compared to other combustion-based electricity generation applications, these are very proficient and also reduce carbon emissions. Thus, the growth in the power generation sector along with an increased focus on generating electricity through sustainable energy sources is projected to propel the growth of gas turbines in the coming years.
An increasing number of stationary power plant installations in emerging economies is projected to drive the demand further. In addition, increasing product penetration in the aerospace application would also benefit market growth in the coming years. The rising adoption of air plasma and High-Velocity Oxygen Fuel (HVOF) technologies in automotive and aerospace applications is expected to drive product demand in these sectors. Heavy investments by leading industry participants, such as Praxair Surface Technologies, for the development of advanced and innovative coating solutions, will also have a positive impact on the market growth during the forecast period.
Thermal Barrier Coatings Market Segmentation
Grand View Research has segmented the global thermal barrier coatings market on the basis of product, application, technology, combination, and region:
Based on the Product Insights, the market is segmented into Metals, Ceramics, Intermetallics, and Others.
- The ceramics product segment led the market and accounted for more than 34% of the global revenue share in 2020. The most commonly used TBC material is yttria-stabilized zirconia, which is a form of ceramic. The key properties of this material include low thermal conductivity, high thermal expansion coefficient, and good erosion resistance.
- The ceramic product segment is expected to remain dominant by growing at the fastest CAGR during the forecast period, owing to the superior thermal resistance properties offered, which enable gas turbines to operate at high operating temperatures with higher efficiencies.
Based on the Application Insights, the market is segmented into Stationary Power Plants, Aerospace, Automotive, and Others.
- The aerospace application segment led the market with a revenue share of more than 31% in 2020. The increasing purchasing power of consumers has resulted in increased air passenger traffic over the past few years. As a result, there is a growing requirement for advanced and highly-efficient aero-engine technologies to cater to the rapidly growing demand in the aviation industry.
- This is expected to have a significant impact on the overall market growth during the forecast period. Expanding aerospace industry in North America is expected to boost the product demand in the region. The presence of key aerospace manufacturers, such as Boeing, is expected to further aid the market growth. Potential customers for TBCs in the aerospace segment are Airbus, Boeing, and Lockheed Martin.
Based on the Technology Insights, the market is segmented into EBPVD, HVOF, Chemical Vapor Deposition, Air Plasma, and Others.
- The air plasma technology segment led the market with a revenue share of more than 35% in 2020. Air plasma technology is used for wearing, corrosion protection, and thermal insulation, as well as for repair and restoration in several industrial sectors.
- The HVOF technology is a TBC process that is used to restore or improve a component's dimensions or properties. This technology provides a variety of benefits including improved performance, improved efficiency, low costs, superior electrical properties, the ability of components to operate in higher/lower temperatures & within harsh chemical environments, and enhanced lifespan of components.
Based on the Combination Insights, the market is segmented into Ceramic YSZ, Al2O3, MCrAiY, Mullite-based, and Others.
- The ceramic Yttria-stabilized Zirconia (YSZ) combination segment led the market and accounted for more than 38% revenue share in 2020. YSZ is a ceramic in which the crystal structure of zirconium oxide is made stable at room temperature by adding yttrium oxide. These oxides are commonly called zirconia and yttria. The most important application of this material is in TBCs for gas turbines.
- Mullite is a compound of alumina and silica, with the formula 3Al2O3-2SiO2. It has low density, good mechanical properties, high thermal stability, low thermal conductivity, and is corrosion and oxidation resistant. However, it gets crystallized, which leads to cracking and delamination. Therefore, this material is suitable as a zirconia alternative for applications such as diesel engines.
