Hardide Coatings Limited is providing cover for the aviation industry with its tungsten carbide-based coating for chrome replacement.

The precision coating is becoming more popular for aviation applications, a trend proven by the acceptance of a three-year coatings approval test program with Airbus. In addition, confidence tests are being conducted at seven key aerospace industry manufacturers.

The coating, which made its Farnborough debut in 2006, provides wear resistance against abrasion, erosion and corrosion on components made from ferrous and nickel-based alloys. ASTM G65 testing has shown that Hardide wears out 40 times slower than abrasion-resistant AR-500, 12 times slower than hard chrome and four times slower than thermal-spray tungsten carbide.

“The unique wear properties of Hardide and the precise nature of the coating process, make it ideal for aerospace applications such as airframe, landing gear, positive locking systems, engine components and actuator-related products,” says Neill Ricketts, managing director of Hardide Coatings Limited. “It is also a cleaner process with less environmental impact than other coating technologies.”
