Approved by Airbus, our Hardide-A coating has been developed and proven as a direct hard chrome replacement. It is a truly conformal coating for standard diameters, complex geometries and internal bores.
Hardide-A matches the standard thickness (50-100 microns) and hardness (800-1200 Hv) of hard chrome plating and outperforms the material in several critical areas:
By matching existing properties, the use of Hardide-A as a hard chrome replacement coating for hard chrome plating (HCP) simplifies the switch as no dimensional changes or drawing re-design is necessary.
During testing, Hardide-A set a new benchmark and demonstrated a better high cycle fatigue endurance than HCP and exceptionally good corrosion resistance when exposed to a salt-fog environment.
Hardide tungsten carbide coatings have been approved by Airbus, BAE Systems, Leonardo Helicopters and Lockheed Martin.
| Property | Hard Chrome | Hardide-A |
|---|---|---|
| Wear resistance | Good | Good |
| Corrosion | Poor (cracked) | Very good resistance to corrosion and acids |
| Fatigue | Significant fatigue debit, typically -20% | Minimal fatigue debit among hard coatings, ranging from +10% to -10% |
| Environmental regulations compliance | Restrictions by OSHA (US) and REACH (EU) | Complies with current regulations; Process ISO 14001 certified |
