Surface Technology

As one of the first industries to fully adopt thermally sprayed coatings into the design of precision engineered components, aerospace applications have been a focus of Bodycote’s thermal spray activities. Bodycote offers over 100 thermally sprayed aerospace applications for a range of material properties.

Advanced thermal spray coating applications include:

  • Thermal management
  • Wear
  • Oxidation
  • Corrosion resistance
  • Sealing systems
  • Vibration, sound absorbance, chrome conversion
  • Component repair

Thermal spray processes:

  • HVOF
  • Plasma
  • Combustion Spray


Ceramic technology:

  • Thermochemical ceramic coatings
  • Ceramic densification
  • Chrome enhancement

Sealing solutions

Bodycote offers a range of sealing solutions to enhance coating performance.

  • Organic sealers
  • Pressure sealing
  • HVOF seal
  • Chrome seal – Bodycote provides a unique, proprietary thin-film technology for both thermal spray and chrome plate, which out-performs conventional organic sealing methods. This technology thermochemically diffuses through the coating, sealing porosity with super-hard ceramic particles.

Precision finishing and inspection

All our coating facilities are equipped with precision and finishing machines capable of achieving surface requirements to the highest standards.

  • Turning
  • Milling
  • Grinding
  • Honing
  • Super-finishing
  • NDT - Non-destructive testing
  • CMM measurement - Coordinate measuring machine
  • In-house laboratories



Under REACH, hard chrome plating is to be heavily restricted; Bodycote Surface Technology acknowledges the mandate to replace chrome with alternative, less harmful materials which meet the legislative criteria. We offer environmentally friendly coating solutions as a direct alternative to chrome plate, providing superior wear and corrosion resistance.

Our HVOF coatings are already used as a direct alternative for hard chrome plate for specific components including:

  • Aircraft landing gear
  • Flight control – Actuation
  • Propeller hubs
  • Gas turbine journals

Coating Solutions


The world’s leading aerospace and defence companies entrust their products to Bodycote’s care.

Bodycote operates an international network of quality accredited facilities, in support of prime aerospace manufacturers and their supply chains, serving the commercial aerospace, defence, helicopter and space markets.

01Landing Gear


The nature and position of this critical component demands both strength and high resistance to wear and corrosion to fulfil design requirements. Environmentally friendly thermal spray processes such as HVOF have superseded traditional coating methods to aid corrosion and wear resistance properties. HVOF-applied tungsten carbide is proven against hard chrome plate as a direct replacement.



Aircraft engines are designed and built to work in extreme conditions and meet ever changing environmental legislations.

Coatings are used to improve engine efficiency by enhancing anti-fretting, anti-galling and wear resistance, providing protection for the base material and extending service life.

03Main Gear Box


In gear box assemblies, all critical parts are designed for resistance to vibration, high pressure and temperatures - typical military helicopter specifications require the main gear box to perform at full power for up to two hours without oil. Bodycote provides surface coating treatments which are essential to high precision, hydraulic control components.

04Main Rotor

Main rotor.

The rotor must withstand centrifugal forces, vibration, abrasion, and corrosion, whilst turning the blades and providing essential inputs to flight control components. HVOF coating is applied to improve resistance, whilst tail rotor blades receive surface coatings to improve their abrasion resistance.

05Drive Shaft

Drive Shaft.

The tail rotor and gearbox’s dependency on the main gear box requires the long drive shaft to be extremely strong, yet lightweight. HVOF coating delivers the required resistance to corrosion and vibration.

06Flight Control

Flight Control.

Flight controls are essential to all aircraft. For example helicopter flight controls are essential to drive the speed and pitch of the rotor blades. Surface technology treatments are applied to improve resistance and increase precision, while maintaining a light weight.



A rocket relies on its propulsion system for thrust at take-off and again in space to change velocity. High nickel and refractory alloys are used to meet these demands and extend component life under these extreme operating environments. A comprehensive range of fused coatings is used to isolate the environment preventing oxidation of the underlying material.



Aerostructures need to be lightweight and at the same time withstand mechanical stresses and vibrations. In addition, pylon components are subjected to high loads and sometimes elevated temperatures. Aluminum and titanium alloys are often used for their low density but have poor sliding properties and a tendency to galling. Thermal spray coatings, such as molybdenum, Tribaloy®, tungsten carbide, copper nicel alloy are solutions that offer temperature resistance, sliding, fretting and anti-galling properties.
