( 2) Fuselage and Wing Structure
Titanium alloy /Composite material connector
Performance improvement : Cold-sprayed aluminum coatings enhance surface conductivity and resistance to fretting wear, addressing the galvanic corrosion issue between composites and metals. (such as the Boeing 787 wing spar splice).
Skin and Fasteners
Performance improvement : Arc-sprayed aluminum-zinc coating (Such as Al-12Zn), with a salt-spray corrosion resistance lifespan exceeding 10 years, replacing the traditional cadmium plating process (ring).
Non-toxic )。
( 3) Landing Gear and Transmission System
Landing gear piston rod
Performance improvement : HVOF-sprayed chromium carbide (Cr3C2-NiCr) coatings exhibit a hardness of over 1100 HV and offer a 70% improvement in impact and wear resistance (e.g., for the landing gear of the Airbus A380).
Gears and Bearings
Performance improvement : Plasma-sprayed molybdenum disulfide (MoS2) solid lubricant coating reduces the coefficient of friction to 0.03, making it suitable for high-load transmission components.
( 4) High-temperature extreme environment components
Rocket engine nozzle
Performance improvement : Supersonic Flame Spraying Zirconium Carbide (ZrC) or hafnium carbide (HfC) coatings, with a temperature resistance exceeding 3000°C and an erosion resistance improved by a factor of three.
Leading edge of a supersonic aircraft
Performance improvement : Explosive spraying (D-Gun) Molybdenum-based coating, with resistance to aerodynamic thermal shock up to 1600°C (e.g., for the X-51A hypersonic aircraft).
( 5) Maintenance and Remanufacturing Field
Blade Wear Repair
Performance improvement : Laser cladding + Plasma spraying of nickel-based alloys (such as Inconel 718) restores component strength to 95% of that of new parts, while reducing costs by 60%.
Airframe crack repair
Performance improvement : Cold-sprayed pure titanium coatings fill cracks in aluminum alloys, restoring the fatigue strength of the repaired area to that of the original material. Over 90%.
II. Thermal spraying technology in Gas Turbine Applications
As a highly efficient power device, gas turbines often face challenges such as high temperatures, corrosion, and wear in their core components. Thermal spraying technology significantly enhances the performance of these components through functional coatings, with specific applications as follows:
- Compressor blade
Problem : Particulate matter in high-speed airflow (Airborne dust and salt spray) cause erosive wear.
Solution HVOF Spraying Tungsten Carbide (WC-Co): Surface hardness reaches 1200 HV (Vickers hardness), with wear resistance improved by a factor of 5 to 8. For example, after adopting this technology, the maintenance cycle for Siemens SGT-800 gas turbine blades has been extended to 40,000 hours.
( 2) Compressor stator vane ring
Problem : High-temperature oxidation and fretting wear.
Solution : Plasma spraying NiCrAIY coating, with a temperature resistance of up to 900℃ and a 30% reduction in frictional wear.
( 3) Combustion chamber inner wall
Problem : The gas temperature reaches as high as 1500°C, leading to metal creep and oxidation.
Solution Thermal Barrier Coating (TBC): Double-layer structure (MCrAIY bonding layer + YSZ ceramic layer), with the substrate temperature reduced by 300–500°C. For example, after adopting TBCs, the GE 9HA gas turbine achieved a thermal efficiency increase to 64%. HVOF Spraying CoNiCrAIY: Temperature-resistant 1100°C, sulfur corrosion resistance improved by a factor of three (laboratory data).
( 4) Flame tube
Problem : Thermal fatigue cracks and localized ablation.
Solution : Laser cladding + Plasma-sprayed Inconel 625, with a post-repair thermal cycle resistance of up to 10^5 cycles.
( 5) Turbine components
Turbine blade
Problem : High-temperature gases cause oxidation, sulfidation corrosion, and thermal stress cracking.
Solution : TBCs+MCrAIY coating : The YSZ surface layer is resistant to temperatures up to 1200℃, and the bonding layer slows down the diffusion of oxidation. For example, the service life of Mitsubishi M701F gas turbine blades has been extended from 20,000 hours to 60,000 hours. Supersonic Flame Spraying Al 2 O 3 -TiO 2: Prevent cooling holes from clogging and enhance film-cooling efficiency. 15%.
( 6) Turbine guide vanes

( 7) Transmission and Sealing System
Bearings and Gears
Problem : Friction, Wear, and Fatigue Failure Under High Loads.
Solution : Plasma spraying MoS 2 Solid lubricant coating The coefficient of friction has been reduced to 0.03, making it suitable for applications involving frequent start-stop operations (experimental results show stability up to 800°C under high-temperature conditions). HVOF-sprayed Cr 3 C 2 -NiCr: Hardness 1100 HV, with a micro-motion wear life extended by a factor of three.
( 8) Gas seal ring
