Thermal Spray Equipment Market Size & Share 2026-2034

Thermal Spray Equipment Market Size

The thermal spray equipment market was valued at USD 13.8 billion in 2025 and is projected to increase from USD 14.5 billion in 2026 to USD 24.1 billion by 2035, representing a 5.8% CAGR.

Demand is rooted in the ability of thermal spray processes to restore or protect components exposed to abrasive wear, corrosion, high friction, and elevated temperatures. Functional multilayer thermal spray coatings are also being developed for applications where a surface must deliver electrical, thermal, or mechanical performance beyond that of the substrate ^{[1]Springer Nature / Journal of Thermal Spray Technology, Thermally Sprayed Functional Coatings and Multilayers, 2023, link.springer.com}.

Aerospace remains a critical demand base because turbine blades, combustion components, landing gear, and other high-value parts require repeatable surface performance under severe service conditions. The 2026 strategic roadmap for thermal spray and PVD coatings identifies aerospace as the largest end-use area, with an estimated share of approximately 33% by 2032 ^{[2]Springer Nature / Journal of Thermal Spray Technology, Innovative Coatings for a Greener Sky: The 2026 Strategic Roadmap for Thermal Spray and PVD Coatings, 2026, link.springer.com}. Regulatory pressure is widening the replacement case for some conventional finishing processes. California's Chrome Plating ATCM prohibited new hard chrome plating facilities from January 1, 2024, and establishes a phased end date for covered existing operations, while aerospace manufacturers in Europe continue to evaluate chromate-free alternatives as REACH authorization requirements evolve.

Application expansion is not limited to heavy industry. Plasma spraying has been demonstrated for high-temperature sensors on silicon carbide substrates, plasma-sprayed hydroxyapatite remains relevant to orthopedic implant surface design, and thermally sprayed aluminum is being assessed as a protective coating option for offshore wind structures. These opportunities increase the addressable range of equipment, but they also raise requirements for material control, process qualification, and traceable operating parameters.

The regulatory transition away from hard chrome is consequential, but it is not a uniform substitution cycle. HVOF WC/Co coatings have been validated for aircraft landing-gear applications as an alternative to hard chrome, yet adoption remains dependent on component-specific testing, approval cycles, and customer confidence in process repeatability. Equipment demand therefore develops alongside qualification activity rather than immediately following a regulatory announcement.

Key Drivers

Increasing industrial applications

Thermal spray equipment supports applications in turbine blades, combustion chambers, boiler tubes, landing gear, engine components, and other parts where substrate replacement is expensive or operationally disruptive. Atmospheric plasma spray can deposit ceramics, metals, and composite material systems, supporting thermal-barrier, wear-resistant, and electrically functional surfaces ^{[3]Oerlikon Metco, Atmospheric Plasma Spray, oerlikon.com}. In industrial gas turbines, MCrAlY bond coats and ceramic topcoats are used to manage oxidation, corrosion, and heat exposure in hot-section components.

Demand also reflects the growing importance of refurbishment. Coating a worn part can be commercially preferable to replacing a large turbine, aerospace, mining, or industrial component, particularly where lead times for new parts are long. This restoration logic broadens equipment demand beyond new manufacturing programs and supports service-oriented coating operations.

Growing demand for surface protection

High-temperature corrosion and oxidation increasingly shape material-selection decisions in energy and process-industry equipment. HVOF-deposited nickel-chromium coatings can provide corrosion and wear resistance, while IN625 thermal spray systems have been studied for high-temperature corrosion protection in approximately 700°C to 900°C environments. Such requirements increase demand for equipment that can consistently control particle temperature, velocity, spray angle, stand-off distance, and heat input.

Offshore renewable-energy infrastructure provides another protective-coating use case. Thermal-sprayed aluminum can protect steel structures in aggressive marine environments, creating a potential link between offshore wind investment and coating-system demand. Electric-vehicle applications remain emerging rather than a quantified market driver, but electrification may broaden demand for thermally managed, wear-resistant, and electrically functional surfaces over time.

Technological advancements

Automation is shifting the competitive basis from standalone spray guns toward controlled coating cells. Oerlikon Metco's Surface Platform integrates process controls, PLC architecture, interfaces for robotic integration, and Accuraspray 4.0 diagnostics that monitor spray-plume characteristics including particle velocity, temperature, intensity, and position. SmartArc systems similarly combine electric-arc spraying with digitalized control functions intended to improve repeatability in wire-spray operations.

Materials development reinforces this shift. Research on nanomaterial-based thermal spray coatings indicates that powder architecture and process control must develop together to realize performance gains from nanostructured feedstocks. Equipment providers that can translate these material advances into stable production windows are better positioned than suppliers offering hardware without application engineering support.

Key Restraints

High initial investment

A complete thermal spray installation requires more than a spray gun. Feedstock delivery, gas and power supply, ventilation, dust collection, chillers, controls, diagnostics, and, increasingly, robotic integration must be configured as a functioning process system. Advanced platforms can include PLC-based control and in-process plume measurement, raising both the initial equipment outlay and the commissioning burden. The investment hurdle is particularly material for smaller coating shops and prospective entrants in Latin America, the Middle East, and Africa, where customer demand may be less concentrated around aerospace or gas-turbine programs.

Capital intensity also creates a procurement trade-off. Buyers may choose lower-cost manual configurations for intermittent work, but those systems can be less suitable where repeatability, digital records, and production throughput are essential. This can delay upgrades even when coating demand is technically available.

Skilled labor shortages

Thermal spray remains a qualification-intensive activity because coating quality is shaped by operator practice, equipment settings, substrate preparation, and inspection discipline. AWS C2.16 requires thermal-spray operators to pass knowledge and performance qualification tests across 12 qualification disciplines covering flame, arc, plasma, and HVOF processes ^{[4]American Welding Society, Guide for Thermal-Spray Operator Qualification, AWS C2.16, pubs.aws.org}. The standard illustrates why capacity cannot be expanded simply by installing equipment.

The labor constraint is most acute where coating providers need to move from repair work into aerospace, medical, or energy applications that require documented process control. Equipment with automation and diagnostics can reduce process variability, but it does not eliminate the need for qualified personnel who can establish parameters, interpret results, and maintain the coating cell.

Automation changes that equation gradually. Digital controls and plume diagnostics can improve repeatability and support more consistent documentation, yet the commercial benefit is greatest when equipment is deployed into sustained production programs rather than occasional repair work. Suppliers that package automation with process-development and qualification capability are therefore likely to capture a larger portion of complex-project spending.

Thermal Spray Equipment Market Segment Analysis

By Equipment Type

Spray systems led the market with USD 3.6 billion in 2025 and are projected to record the fastest growth, at approximately 6.5% CAGR. Their leading position reflects their role as the core production asset for plasma, twin-arc, flame-spray, HVOF, and powder-flame processes. System demand rises when users need control over combustion or plasma energy, particle velocity, spray angle, stand-off distance, and heat input for application-specific coating performance ^{[5]Oerlikon Metco, Surface Platform Complete Thermal Spray Coating Machines, DSE-0139, oerlikon.com}.

Booths generated USD 2.7 billion in 2025, followed by spray guns and nozzles at USD 2.1 billion, dust collection systems at USD 1.6 billion, chillers at USD 1.3 billion, feeder systems at USD 1.1 billion, gas systems at USD 0.8 billion, and other equipment at USD 0.5 billion. These categories are commercially interdependent: dust collection and booths address containment and workplace control, feeders determine powder consistency, and gas systems directly affect the thermal and kinetic conditions of the spray process.

By Surface Type

Metal surfaces represented the largest category at USD 5.7 billion in 2025, equivalent to approximately 41% of market revenue. Metals dominate because thermal spray is extensively used to restore dimensions, manage corrosion, and increase wear resistance in steel, nickel-alloy, titanium, and other engineered components. Polymer surfaces accounted for USD 3.5 billion, ceramics for USD 2.1 billion, composites for USD 1.7 billion, and other surface types for USD 0.8 billion.

The material mix determines equipment specifications. Ceramic thermal-barrier systems require different thermal-management and deposition conditions from metallic wear coatings, while composite and polymer substrates introduce sensitivity to heat input. This diversity supports demand for modular systems and flexible process platforms rather than a single standardized equipment configuration.

By Operation

Automatic systems held the largest share in 2025, reflecting demand for reproducibility, throughput, and process documentation in aerospace, power generation, and high-volume industrial settings. Automated cells can integrate robotic motion with PLC controls and diagnostic tools, improving consistency when complex component geometry or tightly controlled coating thickness is required ^{[6]Oerlikon Metco, SmartArc Electric Arc Wire Thermal Spray System, oerlikon.com}.

Semi-automatic equipment provides a middle ground for coating providers that require greater process control than manual systems but do not have sufficient production volume to justify fully integrated robotic cells. Manual equipment remains important for repair, field-oriented, low-volume, and specialized work, although operator dependence can constrain its use in highly regulated applications.

By End Use Industry

Aerospace is the most significant end-use industry because thermal spray supports turbine, combustion, airframe, and landing-gear applications where component reliability has high economic value. Automotive demand includes engine and wear-component applications, while manufacturing uses thermal spray for restoration and surface enhancement. Oil and gas, energy and power, electronics, biomedical, and other industries contribute demand through corrosion control, thermal insulation, dimensional recovery, and functional-surface requirements.

Biomedical demand is differentiated by qualification requirements and material biocompatibility, whereas electronics applications emphasize functional properties and localized deposition. In power generation, the commercial case is closely linked to extending the usable life of high-temperature parts, particularly where corrosion and oxidation affect availability.

By Distribution Channel

Direct distribution is important for integrated systems because customers often require application engineering, installation, commissioning, and after-sales support. Indirect channels remain relevant for consumables, replacement components, and standardized equipment, particularly where regional service coverage is needed. The balance between direct and indirect routes depends on system complexity: higher-value automated installations generally require closer manufacturer involvement than routine consumable purchases.

Segment economics also diverge by end-use qualification burden. Aerospace and power-generation customers may accept a higher-cost automated platform when it delivers traceability and repeatability across critical components. Repair-oriented and lower-volume users remain more exposed to capital constraints, preserving demand for semi-automatic and manual configurations even as automated systems hold the largest market share.
