Pushing Aerospace Innovation Forward with Precision Coatings That Withstand Extreme Stress and Heat

Reliability and weight optimization are important in aerospace. Our finishes provide thermal spray metal finishes and corrosion resistance to landing gear, turbine blades, and structural parts. Our solutions are of superior quality in terms of stringent aerospace requirements; they are lightweight, and achieve high performance, resistant to oxidation and high temperature, even at high altitude.

Key Advantages of Aerospace Thermal Spray Coatings

Thermal Barrier Protection: Protects combustion components from extreme temperatures, improving overall turbine efficiency and engine life.

Friction and Wear Reduction: Extends the lifespan of landing gear cylinders, actuation systems, and bearing seats subject to intense cyclic load friction.

Corrosion and Oxidation Barrier: Prevents component surface degradation from atmospheric humidity, high-altitude ozone, and jet fuel chemical exposure.

Weight Efficiency and Durability: Enhances the surface properties of lightweight aerospace alloys (like titanium and aluminium) without adding unnecessary bulk.

Aerospace Grade Coatings for Flight Safety and Durability

Aerospace systems require components that operate reliably under extreme conditions, including high combustion heat, high-altitude ozone exposure, extreme thermal shock, and high-velocity gas flows. At Alloy Thermal Spray Pvt. Ltd., we apply specialized thermal barrier coatings (TBCs), wear-resistant carbides, and abradable seals that meet the rigorous standards of the aerospace industry, protecting jet engine parts and landing gear systems.

Our ceramic thermal barrier coatings, such as Yttria-Stabilized Zirconia (YSZ), are applied to turbine blades and combustion chambers to insulate metal substrates from hot gas streams. This insulation enables higher engine operating temperatures, which directly translates to improved fuel efficiency and engine thrust. Additionally, our coatings protect critical landing gear cylinders from impact wear and corrosion during takeoffs and landings.

Key Features & Technical Capabilities

Thermal Shock Insulation: Allows metal components to survive temperatures exceeding their melting points.

Erosion and Oxidation Shielding: Protects gas turbine blades from high-speed particle erosion and scaling.

Weight Optimization: Thin coating layers replace heavy solid alloys, reducing overall aircraft weight.

Abradable Seal Clearance: Maximizes compressor efficiency by maintaining tight clearances between blade tips.
