Hardide-A has been developed specifically to meet the needs of the aerospace industry. It is an environmentally compliant and technically superior replacement for HCP and HVOF coatings, providing enhanced protection against corrosion and chemically aggressive media, wear, galling, fretting and fatigue. Hardide-A matches HCP in thickness and hardness and outperforms the material in several key properties including enhanced protection against corrosion, wear and chemically aggressive media. The transition from hard chrome to Hardide-A is facilitated for customers as no significant changes are necessary in part dimensions or drawings.
Hardide-LA is an ultra-low temperature variant of Hardide-A which is suitable for coating grades of steel and alloys sensitive to a 500°C / 932°F process temperature. It is produced at a significantly lower temperature – below 370°C / 698°F.
– Can be applied to internal and external surfaces and complex shapes uniformly
– Smooth, uniform as-coated surface finish minimises expensive grinding and finishing operations.
– Easily applied to a wide range of metallic substrates including ferrous and nickel-based alloys, and most grades of stainless and carbon steels
– Applications include door pins, bushes, bearings, hooks, catches, landing gear, flap tracks and slats, sleeves, rods, valves, pistons, actuators, compressors, shafts, hydraulic and pneumatic cylinders
Hardide Coatings’ UK and USA manufacturing sites are approved to ISO 9001 and aerospace AS 9100 certification. The UK site is also accredited to Nadcap and ISO 14001.
