Market Overview

The global thermal spray coatings market size was valued at USD $12.26 billion in 2022. It is estimated to reach USD $19.13 billion by 2031, growing at a CAGR of 5.06% during the forecast period (2023–2031).

In thermal spray coating processes, the substrate is struck by a stream of finely divided, high-velocity particles that are either molten or semi-molten and are used to deposit coatings. These procedures enhance or repair a solid substance's surface using finely powdered source material or, occasionally, a molten metal wire split into tiny droplets. The method protects against wear, erosion, cavitation, corrosion, abrasion, and heat while coating various materials and components. Furthermore, thermal spray can achieve lubricity, high or low friction, sacrificial wear, chemical resistance, and many other desirable surface qualities. These coatings are an effective alternative to several surface treatments such as nickel and chrome plating, nitride or heat treat processes, anodizing, and weld overlay. Depending on the coating material, they are typically thicker than plating, in the range of .002"-.025" thick.

Market Dynamics

Market Drivers

  • Growing Demand from the Healthcare Industry

In healthcare, thermal spray coatings are widely employed for numerous purposes, including pacemakers, dental implants, prosthetics, and orthopedics. These coatings exhibit wear resistance, corrosion resistance, high temperature, and biocompatibility. These coatings are porous and bio-active, enabling biomedical engineers to design implants more suited to interact with bone tissue. Thermal sprayed ceramic coatings on medical implantable exhibit easier cleaning and reprocessing due to hydrophobic properties. Moreover, they are 100% anti-allergic due to the absence of chromium and nickel on the surface layer, providing comfort to the patient.

The rising health concerns associated with a sedentary lifestyle and poor eating habits are likely to increase the number of patients suffering from various diseases, which is expected to boost the demand for implantable surgeries. Moreover, the rising geriatric population and increasing road accidents drive the demand for surgeries and medical devices. All these factors fuel the need for thermal spray coating and are expected to continue during the review period.

  • Thermal Spraying Substituting Electroplating Processes

Thermal spraying is commercially competitive regarding hard chrome plating. Some benefits include energy costs, capital costs, material diversity, waste disposal, and space. For plating, about 15 W of energy is needed per square inch. The energy expenses increase proportionately with the size of the part. For thermal spraying, part size impacts the coating application time and is subject to the process used, while the energy costs can be similar. The relative capital cost for setting up facilities with the same production capacity is considerably lower for thermal spraying than chrome plating.

The disposal of effluents from the plating process is expensive due to the toxicity of hexavalent chromium. On the other hand, thermal spraying makes harmful waste, such as metallic dust, which can be thrown away quickly. Furthermore, the thickness of chrome plating is challenging to control. Certain advantages of thermal spraying include a higher deposition rate, denser coatings, fewer process steps, and no limitation on component size. The various benefits of thermal spraying over electroplating will likely drive market growth in the coming years.

Market Restraint

  • Disadvantages Associated with Thermal Spraying Processes

Thermal spray coatings have various disadvantages. For instance, plasma spray coatings restrict surface access, and small-diameter internal bores are challenging as it is a line-of-sight process requiring automated gun manipulators. The high temperatures associated with the plasma jet can result in carbide decomposition or excessive oxidation when spraying in the air, giving carbide coatings with lower hardness or metallic coatings with higher oxide levels than HVOF-sprayed coatings. In addition, there is no evaluation or testing method for assessing how well the layer has adhered to the substrate. The process requires measures to combat noise, light, dust, and fumes, which is expected to hamper the market growth during the forecast period.

Market Opportunities
