• The expansion of gas turbine capacity in energy transition infrastructure, and the rapid commercial adoption of cold spray technology across electric vehicle and electronics manufacturing driven by an accelerating aerospace Supercycle. According to the latest report published by Global Market Insights Inc., demand across all service modes offsite job shops, onsite field services, and in house OEM operations is expanding in parallel, though the pace of growth is bifurcating between premium aerospace certified facilities and general industrial service providers. At the segment level, cold spray stands out as the fastest growing technology at a 13.1% CAGR from 2025 to 2035, as its ability to deposit materials below their melting point makes it uniquely suited for temperature sensitive substrates in EV battery enclosures and semiconductor equipment components. The structural driver underlying the broader market expansion is the convergence of three long cycle demand patterns: continued fleet growth in commercial aviation, the global rollout of gas turbines for power generation, and the emergence of India and the Middle East and Africa as industrially active thermal spray markets.
• Global commercial aviation MRO expenditure reached approximately USD 119 billion in 2025 the strongest multiyear growth cycle since the post 9/11 recovery.^{[1]International Air Transport Association (IATA), iata.org} Thermal spray services are structurally embedded in the MRO value chain: every engine shop visit involves a CFM LEAP 1A or LEAP 1B engine requires plasma sprayed thermal barrier coatings on combustor liners, turbine shrouds, and blade leading edges, as well as HVOF applied bond coats on high pressure turbine blades. The LEAP engine fleet, approaching approximately 15,000 engines in service by 2025, is entering its first major shop visit cycle, generating a coating workload that NADCAP certified facilities across North America and Europe are managing under capacity constrained conditions. The backlog at certified aerospace coating facilities grew materially through 2024 and 2025, creating a supply demand imbalance that is simultaneously a short term growth catalyst and a medium term market structuring force.
• The global pivot toward natural gas as a transition fuel has driven a sustained increase in combined cycle gas turbine (CCGT) orders and, by extension, in TBC and MCrAlY bond coat service demand for gas turbine hot section components.^{[2]International Energy Agency (IEA), iea.org} Gas turbine net additions reached 92 GW globally in 2024, and forward order books across GE Vernova, Siemens Energy, and Mitsubishi Power extend well into the late 2020s. Each turbine commissioning cycle generates a service revenue tail of 15 to 20 years, establishing a durable demand base for plasma spray and VPS operators specializing in turbine hardware. The wind energy restoration sub segment contributes an additional demand layer, with thermal spray used to refurbish aging turbine main shaft bearing surfaces across onshore and offshore fleets in Europe and North America.
• Cold spray technology's structural advantage material deposition without thermal stress positions it as the process of choice for temperature sensitive substrates in EV motor housings, battery enclosures, and copper bus bar repairs.^[3] The EV cold spray sub segment within the automotive end use category is projected to grow from USD 151 million in 2025 to USD 464 million in 2035, a CAGR exceeding 11%. Semiconductor equipment components, specifically yttria coated chamber liners and aluminum spray process kits used in plasma etch chambers, represent a second high growth application pathway, with demand linked to advanced node capacity investment by leading memory and logic chip manufacturers in Japan, South Korea, and the United States.

Thermal Spray Service Market Trends

• The most consequential demand driver in the thermal spray service industry over the 2025 to 2030 horizon is the ongoing aerospace MRO supercycle. Global airline maintenance, repair, and overhaul expenditures reached USD 119 billion in 2025, up from USD 79 billion in 2022 a 50% absolute increase in three years with forward projections from IATA indicating the market will sustain above USD 140 billion annually through 2030. Thermal spray services are structurally embedded in the MRO value chain: every engine shop visit involving a CFM LEAP 1A or LEAP 1B engine requires plasma sprayed thermal barrier coatings on combustor liners, turbine shrouds, and blade leading edges, as well as HVOF applied bond coats on high pressure turbine blades. The LEAP engine fleet is entering its first major shop visit cycle, generating a coating workload that NADCAP certified facilities across North America and Europe are managing under capacity constrained conditions.
• At the coating material level, the thermal spray service market is undergoing a structurally important transition away from legacy flame spray and electroplating processes toward advanced ceramic and carbide coating systems. Yttria stabilized zirconia (YSZ), deployed via atmospheric plasma spray (APS), remains the dominant thermal barrier coating for gas turbine hot sections and is projected to account for 40% of the ceramics sub segment through 2035 a revenue base of USD 1,399 million. Tungsten carbide cobalt (WC Co), applied by HVOF, is consolidating its position as the preferred wear resistant coating for O&G valve seats, pump sleeves, and industrial cutting tool surfaces, at 53% of the carbides and cermets sub segment at USD 1,470 million by 2035.
• The underlying driver is tightening performance and environmental regulation: ECHA's inclusion of hexavalent chromium compounds on the REACH Authorization List is accelerating the conversion of hard chrome plating operations to HVOF tungsten carbide alternatives across aerospace, defense, and hydraulic cylinder manufacturing.^{[4]European Chemicals Agency (ECHA), echa.europa.eu} Airbus cited HVOF coating qualification milestones on A320neo landing gear components in 2023, a development that has accelerated qualification timelines at Tier 1 aerospace component manufacturers across France, Germany, and the UK. The more consequential second order effect is the skill and equipment investment required: HVOF system capital expenditure of USD 500,000 to USD 1,000,000 per gun assembly is driving consolidation toward larger, better capitalized operators who can amortize equipment costs across sufficient volume.
