Under REACH, hard chrome plating is 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 and plasma coatings are already being designed and used as a direct alternative for hard chrome plate for specific components including:

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

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 Environmentally friendly thermal spray processes such as HVOF have superseded traditional coating methods to aid corrosion and wear resistance properties.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 gearbox assemblies, all critical parts are designed for resistance to vibration, high pressure and temperatures - typical military helicopter specifications require the main gearbox 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.

he 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 gearbox 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 lightweight.



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 are 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. Aluminium 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, CuNiI alloy are solutions that offer temperature resistance, sliding, fretting and anti-galling properties.
