The global thermal spray coatings market size was valued at USD 9.6 billion in 2025 and is projected to grow from USD 9.98 billion in 2026 to USD 13.62 billion by 2034, registering a CAGR of 3.96% during the forecast period from 2026 to 2034. Asia Pacific dominated the thermal spray coatings market with a market share of 36.8% in 2025.
Thermal spray coatings are protective surface coatings applied by spraying molten or semi-molten materials onto a substrate using high-temperature processes. The coating materials, which may include metals, ceramics, polymers, or composites, form a durable layer that enhances surface properties without significantly affecting the base material. Thermal spray coatings are widely used to improve wear resistance, corrosion resistance, thermal insulation, oxidation resistance, and component durability in industries such as aerospace, automotive, energy, manufacturing, and oil and gas.

Advanced Thermal Spray Processes Improve Coating Performance
Thermal spray technology is moving toward more controlled deposition processes that improve coating density, oxidation resistance, surface properties, and service performance. High-velocity air fuel (HVAF), high-velocity oxy-fuel (HVOF), suspension spraying, and other advanced processes are being evaluated to achieve more precise coating structures for demanding applications. This transition is changing how manufacturers select thermal spray processes, with greater attention to coating microstructure and long-term performance rather than only deposition speed or basic wear protection. These developments are supporting thermal spray coatings market trends by expanding the range of performance characteristics that thermal spray technologies can deliver.
In January 2025, research comparing atmospheric plasma spray, suspension HVOF, and filament HVOF coatings on nickel-chromium heater materials found that suspension HVOF produced thin, nearly oxide-free coatings, demonstrating the performance advantages achievable through advanced spray approaches.
Digitalization and Process Monitoring Become More Important
Thermal spray operations are increasingly incorporating digital technologies for process monitoring, control, modeling, and optimization. These technologies can help manufacturers better understand spray conditions and coating formation while reducing process variability. The shift is particularly relevant for aerospace and other industries where coating quality must remain consistent across complex components. As manufacturers integrate sensors, simulation, automated control, and data-based optimization, thermal spray production is moving toward more digitally controlled manufacturing environments.
In November 2025, the Journal of Thermal Spray Technology published a comprehensive review of Industry 4.0 integration in thermal spray processes, covering monitoring, control, optimization, and digital technologies used to improve thermal spray manufacturing and applications.
Demand for Corrosion Protection Supports Advanced Coating Adoption
Thermal spray coatings are increasingly used where corrosion can shorten component life or increase maintenance requirements. Coating a relatively economical substrate with a protective material can provide resistance against aggressive environments while extending component service life. This creates demand across energy, industrial equipment, chemical processing, and other applications where components are exposed to corrosive operating conditions. The ability to combine corrosion protection with other properties such as wear resistance further increases the usefulness of thermal spray technologies.
In September 2025, research on thermal spray coatings for concentrated solar power thermal-energy-storage systems found that Inconel-625 coatings reduced corrosion by 92% compared with an SS 316L substrate during the investigated conditions, demonstrating the potential of thermal spraying for protecting components exposed to molten salts.
Process Complexity Can Increase Manufacturing Requirements
Thermal spraying requires careful control of factors such as substrate preparation, spray parameters, particle behavior, coating thickness, porosity, and residual stresses. Variations in these parameters can affect the final coating's mechanical and thermal performance. This creates a technical barrier for manufacturers because achieving repeatable results requires specialized equipment, trained personnel, process monitoring, and quality-control procedures. The complexity becomes more pronounced when coatings are applied to components with irregular geometries or demanding performance requirements.
In June 2025, a study published in Coatings developed a multi-scale model to evaluate residual stresses in atmospheric plasma-sprayed coatings while varying substrate geometry, pre-heating temperature, and coating thickness, highlighting the number of process variables that can influence coating behavior.
Thermal Spray Opens New Applications for Functional Surface Engineering
The market has opportunities to move beyond conventional wear and corrosion protection toward coatings that provide specialized surface characteristics. Thermal spray processes can be engineered to produce surfaces with particular wettability, thermal behavior, electrical characteristics, or friction properties. This enables coating suppliers to address specialized applications where conventional protective coatings may not provide the required combination of properties.
In September 2025, researchers demonstrated a one-step HVOF process for producing superhydrophobic stainless-steel coatings, achieving a water contact angle above 160° and a roll-off angle of approximately 5°. The result illustrates how thermal spray can be adapted to create specialized functional surfaces.
Developing New Coating Materials Requires Performance Validation
Thermal spray coating developers face the challenge of proving that new materials can provide reliable wear, erosion, corrosion, and mechanical performance under practical operating conditions. Advanced feedstocks can offer improved properties, but their behavior during spraying and subsequent service must be evaluated carefully. This creates a need for extensive laboratory testing and process optimization before new coating materials can move into demanding commercial applications.
In June 2025, research published in Wear evaluated rare-earth-element-doped AlCoCrFeMo high-entropy alloy coatings produced through flame spraying and investigated their mechanical, wear, and corrosion characteristics, highlighting the development work required to qualify advanced coating materials for demanding applications.
