The global thermal spray coatings market was estimated to reach USD 10.46 billion in 2023 and is projected to grow at a compound annual growth rate (CAGR) of 4.8% from 2024 to 2030. This growth trajectory is largely influenced by the increasing application of thermal spray coatings across a diverse range of end-use industries, including automotive, aerospace, medical, industrial gas turbines, printing, steel, and pulp and paper.

A significant factor contributing to the market's expansion is the rising deployment of gas turbines in various applications such as helicopter engines, tanks, ships, and locomotives. The inherent properties of thermal spray coatings, specifically their resistance to high temperatures and corrosion, make them ideal for protecting critical components in environments characterized by extreme heat and moisture. This protective capability is essential in preventing damage to parts exposed to fire and other harsh conditions.

Key Properties and Regulatory Influences

Thermal spray coatings offer a range of beneficial properties, including:

• Wear Resistance: They are designed to withstand abrasion, cavitation, and erosive forces, ensuring longevity and durability of components.
• Chemical Resistance: These coatings protect substrates from corrosive environments, extending the lifespan of the underlying materials.
• Electrical Insulation: Certain thermal spray coatings provide electrical insulation, making them suitable for applications in electronics and electrical components.
• Adhesion: Enhanced adhesion between the substrate and the top layer improves the overall performance of coated components.

Additionally, stringent regulatory frameworks established by the U.S. Environmental Protection Agency (EPA), REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals), and the Occupational Safety and Health Administration (OSHA) are compelling coating manufacturers to seek sustainable alternatives. These regulations aim to limit the use of hard chrome plating, which generates carcinogenic byproducts, thus further stimulating the demand for environmentally friendly thermal spray coating solutions across various industries.

In North America, the United States has historically accounted for the largest share of the regional market as of 2021, driven by robust industrial activities and a focus on advanced manufacturing technologies.

Material Segmentation Insights

The ceramic materials segment dominated the thermal spray coatings market, commanding over 31.0% of revenue share in 2023. This dominance is primarily due to the excellent adhesion properties of ceramic coatings, which enable them to effectively bond to surfaces and provide critical benefits such as corrosion protection, thermal barriers, dielectric strength, and resistance to sliding wear. The thermal barrier properties of ceramics make them particularly useful in heat insulation applications, enhancing the operational efficiency of components in high-temperature settings and prolonging their service life.

Another important category within thermal spray coatings is abradable materials. These materials are specifically engineered to wear down when in contact with abrasive substances, thereby safeguarding the underlying material from damage. They play a crucial role in gas turbine engines, particularly for clearance control. This function is vital for managing dimensional changes that occur due to thermal expansion when rotating assemblies and blades heat up and cool down during operation.

As a result, abradable materials find extensive applications in aviation gas turbines, power generation, and both gas and steam turbines. Their use in coating shafts, drive collars, labyrinth seals, compressor wheels, compressor impellers, and turbine wheels is expected to further bolster their growth in industries such as aerospace, steel, industrial gas turbines, and automotive.

Additionally, carbide coatings are employed in sectors such as power generation, pulp and paper, and automotive components. These coatings provide essential resistance to abrasion, adhesion, erosion, and fretting, making them ideal for high-demand applications. Their high melting point and ability to retain strength, hardness, and wear resistance even at elevated temperatures make them suitable for coating components like gate valves, fixtures, pump housings, and wear plates. Given their application on costly components, carbide-based thermal spray coatings are anticipated to see increased consumption, further driving market growth.
