The rising use of gas turbines in helicopter engines, tanks, ships, and locomotives is expected to help augment the demand for thermal spray coatings due to their high temperature and corrosion resistance, which protects the parts against fire in high-temperature and moisture-laden conditions.

The properties provided by thermal spray coatings include wear resistance against abrasion, cavitation, and erosive forces, as well as chemical resistance, electrical insulation, and improved adhesion between the substrate and the top layer of components. The stringent regulations by the U.S. EPA, REACH, and OSHA regarding the curtailment of hard chrome plating, which produces a byproduct recognized as a carcinogen, influence the coating manufacturers to adopt sustainable solutions that can further propel the market growth in various end-use industries.

This is attributed to the high demand from power generation plants for industrial gas turbines, which are expected to witness a surge in gas turbine demand due to the policy transition of the U.S. government toward replacing coal with natural gas for electricity generation. According to the Rural Health Information Hub, there are currently 46 million adults over the age of 65 years living in the U.S., which is expected to grow to 90 million by 2050. The rising geriatric population and improved healthcare services in the U.S. are expected to drive the market for orthopedic implants required in knee cap replacement surgery, and are anticipated to grow the market in the region.

Market Dynamics

Material Insights

The ceramic material segment dominated the thermal spray coatings industry, accounting for a revenue share of 32.1% in 2025. This is attributed to the fact that ceramic coatings possess excellent adhesion properties, which enable them to adhere to the surface and provide corrosion protection, thermal barrier, dielectric strength, and sliding wear resistance to the coated materials. Due to the thermal barrier properties, ceramics are often utilized in heat insulation applications to improve the operational efficiency of components in high-temperature environments and extend the service lifespan. Abradable materials tend to wear when rubbed against a highly abrasive material while protecting the underlying material and leaving it damage-free. It is used for coating gas turbine engines for clearance control, which helps prevent the change in dimensions that occur due to thermal expansion since the rotating assemblies and blades heat up and cool down during operation.

The abradables segment is expected to grow at the fastest CAGR of 5.4% from 2025 to 2033, due to increasing demand from aerospace and industrial gas turbine applications. These coatings enhance engine efficiency by enabling tighter clearances between rotating and stationary parts, thereby reducing fuel consumption and emissions. Rising aircraft production, expanding MRO activities, and the need for higher turbine performance and safety further support the strong growth of abradable thermal spray coatings.

Technology Insights

The plasma spray technology segment dominated the thermal spray coatings market, accounting for a 33.4% revenue share in 2025. This is attributed to the fact that this process provides the advantage of spraying metallic and ceramic materials onto various surfaces with excellent bond strength, while minimizing substrate distortion on both large and small components. It provides electrical conductivity, clearance control, wear resistance, and heat & oxidation resistance to the substrate surface. The plasma thermal spray coatings process is used on printing rolls, gas turbines, industrial diesel engine piston rings, and oil & gas machinery. Moreover, this process is adopted widely in coating orthopedic and dental implants due to its ability to produce a dense and porous surface layer, surface roughness, and microstructure of the coatings depending upon the requirement.

The growing incidence of orthopedic injuries and diseases, such as arthritis and osteoarthritis, combined with the rapid rise in the geriatric population, particularly in Europe and North America, is driving the demand for orthopedic implants, which in turn may fuel the growth of plasma thermal spray coatings technology. Cold spray technology utilizes thermal energy to soften or melt the feedstock, then impacts particles at high velocity onto a substrate. This technology finds use in corrosion protection, electronics, and the automotive industry due to its compatibility with various alloys, metals, composites, and refractory metals. The application of cold spray technology is driven by its expansion into other end-use sectors, contributing to its growth.

For instance, members of the 28th Maintenance Squadron’s Additive Manufacturing and Rapid Repair Facility conducted a cold spray repair to a B-1B Lancer Forward Equipment Bay (FEB) panel. This type of repair increases aircraft availability at a reduced operational cost through the sustainment of legacy aircraft components and can positively impact segment growth in the aerospace sector. High-velocity oxy-fuel (HVOF) was the subsequent dominating technology in the global market. It is used to restore or improve a component’s properties or geometry, enabling the extension of the equipment’s life.

The advantages of HVOF over other technologies, such as lower porosity due to greater particle impact velocities, higher strength bond to the underlying substrate, lower oxide content, smooth surface, better wear resistance, and improved corrosion resistance, drive the segment growth. However, HVOF-sprayed coatings can be highly complex, as their properties & microstructure depend on numerous processing variables. Additionally, the powder sizes are restricted to approximately 5-60µm, which further limits its application.

Application Insights

The aerospace application segment dominated the thermal spray coatings industry, accounting for a 32.0% revenue share in 2025. This is attributed to the high demand for products in aerospace applications, as parts in an aircraft are prone to degradation due to particle erosion, hot corrosion, metal-to-metal wear, and fretting. According to a report published by Deloitte in 2021, the pandemic-induced impact on customer demand and pricing pressure has led many aerospace manufacturers to seek new opportunities for aftermarket services revenue. This is expected to increase Maintenance, Repair, and Overhaul (MRO) work, which can boost product demand in the aerospace industry.

The medical segment is expected to grow at the fastest CAGR of 5.3% from 2025 to 2033, driven by the rising global demand for orthopedic and dental implants. Thermal spray coatings are widely used to enhance biocompatibility, corrosion resistance, and bone integration of implant surfaces. Factors such as an aging population, increasing incidence of joint disorders, higher surgical procedure volumes, and continuous advancements in implant materials and surface engineering technologies are strongly supporting the growth of thermal spray coatings in medical applications. 

Regional Insights

North America dominated the thermal spray coatings market in 2025, accounting for the largest revenue share of 28.5%, driven by its robust aerospace, defense, and industrial manufacturing sectors. The region has a high concentration of aircraft OEMs, gas turbine manufacturers, and well-established MRO facilities, which drive consistent demand for advanced coating solutions.
