Thermal spray coatings protect components that run hot, wear fast, or corrode easily. They are used in jet engines, power turbines, and orthopedic implants. According to Grand View Research, the thermal spray coatings market looks like this:
- Market size in 2025: USD 11.3 billion
- Estimated size in 2026: USD 11.8 billion
- Projected size by 2033: USD 16.2 billion
- Growth rate: 4.7% CAGR from 2026 to 2033
- Largest region: North America, with a 28.5% revenue share in 2025
- Fastest-growing region: Asia Pacific, at a projected 5.5% CAGR from 2026 to 2033
Core Market Segmentation Overview
The report divides the market by material, technology, application, and region.
By material. Ceramics led in 2025 with a 32.1% revenue share. Their adhesion, corrosion protection, thermal barrier performance, and wear resistance make them a strong fit for heat-intensive uses. The full material list also covers metals, intermetallics, polymers, carbides, abradables, and others. Abradables are the fastest-growing material, at a projected 5.4% CAGR through 2033. Gas turbine engines use them for clearance control, and tighter clearances improve efficiency and cut fuel use and emissions.
By technology. Plasma spray was the largest segment in 2025, with a 33.4% share. It bonds well to metals and ceramics, limits distortion of the part, and produces the dense-yet-porous surfaces that orthopedic and dental implants need. HVOF is the next most dominant technology. It offers low porosity, strong bonding, and good wear and corrosion resistance. Cold spray, flame spray, and electric arc spray complete the segmentation.
By application. Aerospace held the largest share in 2025, at 32.0%. Aircraft parts suffer from particle erosion, hot corrosion, and fretting, and growing maintenance, repair, and overhaul (MRO) activity keeps demand steady. The other applications are industrial gas turbines, automotive, medical, printing, oil and gas, steel, and pulp and paper. Medical is the fastest-growing application, at a projected 5.3% CAGR. Aging populations, more joint disorders, and rising implant procedures are behind that growth.
By region. The report covers North America, Europe, Asia Pacific, Latin America, and the Middle East and Africa, with country-level analysis for the U.S., China, India, Japan, Germany, Brazil, Saudi Arabia, and others.

Prominent Industry Trends
- Power generation is a major growth engine. Gas turbines, steam turbines, boilers, and heat exchangers operate under extreme heat, pressure, and corrosion, and coatings extend their life. Continued growth in electricity generation, along with a shift from coal to natural gas in some markets, supports demand for industrial gas turbine coatings.
- Regulation is pushing hard chrome out. Rules from the U.S. EPA, REACH, and OSHA are pushing manufacturers to replace hard chrome plating, whose byproduct is a recognized carcinogen. Thermal spray is a cleaner alternative. The same regulatory pressure is also a restraint, since compliance means investing in ventilation, fume extraction, protective equipment, and monitoring.
- Aerospace MRO and repair applications are expanding. Coatings are increasingly used to restore parts as well as protect new ones. Cold spray repair of a B-1B Lancer equipment bay panel is one example. It shows how the technology can raise aircraft availability at lower cost.
- Medical implants are creating new demand. An aging population and rising rates of arthritis and osteoarthritis are increasing demand for knee and hip implants. Plasma-sprayed coatings improve biocompatibility and bone integration.
- Asia Pacific is catching up quickly. Industrialization, growing aircraft fleets, new power capacity, and higher vehicle production in China, India, and Japan drive the region's growth. A growing base of local coating service providers and supportive industrial policies add to it.
- Investment in advanced capabilities. In June 2024, Oerlikon opened an Advanced Coating Technology Center in Westbury, NY. It combines thermal spray and PVD capabilities for aerospace and gas turbine coatings, including environmental barrier coatings for ceramic matrix components. In January 2024, Flame Spray Inc. announced a USD 2.5 million expansion in South Carolina to serve gas turbine and aerospace customers.
Major Key Players
Grand View Research names Oerlikon Metco and Linde plc as the two dominant manufacturers.
