Thermal Spray Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Thermal Spray Market Trends and Insights

Hard-Chrome Replacement Across Hydraulics

In 2024, the UK denied authorizations for chromium trioxide, prompting hydraulic-cylinder manufacturers to seek alternatives. They turned to HVOF and HVAF coatings, achieving wear resistance akin to hard chrome while sidestepping carcinogenic waste. In a notable shift, Airbus and Boeing, in 2025, revised their material specifications. They now permit deposits of up to 300 µm, either tungsten-carbide-cobalt or chromium-carbide-nickel-chromium, on landing-gear shafts. This change has ignited a surge in demand for retrofitting automated masking and sub-5 µm grinding systems. Meanwhile, North American OEMs have discovered that investing in spray cells yields a return within 18-24 months by sidestepping wastewater fees. Furthermore, the ISO 14917 certification has emerged as a pivotal procurement benchmark, leading to a wave of consolidation among coating job shops that can afford third-party audits.

Light-Weight, High-Temp Alloys in Narrow-Body Jet Engines

Next-gen turbofans, boasting pressure ratios exceeding 50:1, are pushing turbine-inlet temperatures beyond 1,500 °C. This surge in temperature necessitates the use of multilayer YSZ thermal-barrier coatings, complemented by rare-earth-doped bond coats, to effectively resist CMAS attacks^{[1]Michael Mauer, “Process Diagnostics and Control in Thermal Spraying,” Journal of Thermal Spray Technology, springer.com}. Utilizing suspension plasma spray (SPS), manufacturers achieve columnar YSZ microstructures that boast lower thermal conductivity, resulting in an extended time-on-wing. Industry giants are turning to solution-precursor plasma spray (SPPS) for applying environmental-barrier coatings on their ceramic-matrix-composite shrouds. In a strategic move to mitigate rare-earth risks, engine OEMs are now stockpiling scandia- or dysprosia-doped feedstock. This decision, while safeguarding against supply chain vulnerabilities, has led to an inflation of working capital requirements, particularly challenging for smaller coaters.

Hydrogen ICE and E-Powertrain Cylinder Bore Wear Solutions

Hydrogen embrittlement causes bore wear in heavy-duty hydrogen engines. However, iron-based thermal-spray coatings help mitigate this issue by trapping hydrogen in controlled-porosity micro-voids^{[2]Daroonparvar M. et al., “Hydrogen Embrittlement Resistant Coatings: A Review,” coatings, mdpi.com}. Daimler Truck and Volvo Group are in the process of qualifying arc-sprayed FeCrAlY coatings, targeting long-term durability. In response to Euro 7 brake-particle regulations, thermal-spray rotors have been developed that can reduce dust emissions significantly. Additionally, wire-arc systems, which deposit aluminum-bronze or molybdenum at a high rate, have managed to lower per-part costs sufficiently to rival traditional machining methods.

High-Entropy Alloy Coatings for Geothermal and Space Probes

High-entropy alloys from the CoCrFeNi family endure temperatures greater than 800 °C and resist corrosive brine. This resilience has led to geothermal tests, revealing that these alloys boast a significantly longer lifespan than Inconel 625. Recent laser-assisted cold-spray trials achieved near-dense CoCrFeNiTi repairs on rocket nozzles, showcasing minimal oxidation. However, with gas-atomized HEA powders remaining expensive, adoption faces hurdles. The challenge persists until additive suppliers can upscale directed-energy-deposition wire routes, effectively combining near-net printing with thermal-spray finishing.

Skilled-Operator Scarcity in Asian and LATAM Job-Shops

Mastering thermal-spray proficiency typically requires several months. However, as vocational pipelines struggle to keep pace, many shops in Southeast Asia and Latin America face significant vacancies. Recently, fewer new Level II inspectors have received global certification compared to earlier years. Productivity continues to be affected as operators migrate to higher-wage markets in the GCC, and unreliable power grids destabilize plasma torches. Most shops, earning modest revenues, find it challenging to invest in robotic automation, especially with vision-guided cell costs remaining high.

Volatile WC-Co and Rare-Earth Oxide Supply Chain

In early 2025, a significant increase in tungsten-carbide prices followed China's 2024 prohibition on tungsten-processing technology. This move tightened profit margins for coaters in North America and Europe. While domestic powder plants, backed by the U.S. defense sector, are on the horizon, they are not expected to achieve full scale until later this decade. In 2025, fluctuations in spot prices for yttria and dysprosia added complexity to fixed-price contracts in the aerospace sector. Meanwhile, smaller job shops, lacking the capacity to secure multi-ton supply agreements, are increasingly outsourcing work to integrated competitors equipped with captive atomizers.
