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 Environmentally friendly thermal spray processes such as HVOF have superseded traditional coating methods to aid corrosion and wear resistance properties.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.
mAIN 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.
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.
