1. What Are Thermal Spray Coatings?
Thermal spray coatings are surface engineering solutions where materials (metals, ceramics, polymers) are heated/melted and sprayed onto substrates to form protective or functional layers. These coatings provide:
- Wear & corrosion resistance
- Thermal insulation
- Improved adhesion & longevity
- Electrical conductivity/insulation
Common applications include turbine blades, medical implants, automotive parts, and oil & gas pipelines 13.
2. Market Growth Drivers
A. Rising Demand from Aerospace & Automotive Sectors
- The aerospace segment dominates (32% market share) due to coatings on engine components, landing gear, and turbine blades to withstand extreme temperatures 14.
- Automotive adoption is growing for lightweight, fuel-efficient coatings on pistons, cylinders, and exhaust systems 5.
B. Shift from Chrome Plating to Eco-Friendly Alternatives
- Strict environmental regulations (e.g., EPA, REACH) against toxic hexavalent chromium are pushing industries toward HVOF and plasma spray coatings 46.
C. Healthcare & Biomedical Applications
- Orthopedic and dental implants use thermal spray coatings (e.g., hydroxyapatite) for biocompatibility and wear resistance 36.
D. Renewable Energy Expansion
- Coatings protect wind turbines, hydropower systems, and geothermal pipes from erosion, boosting demand in clean energy 68.
