test program with Airbus
Hardide Coatings Limited, which has developed a tungsten carbide-based coating for chrome replacement programs, has entered into a three-year coatings approval test program with Airbus and has tests being performed at seven other aerospace industry manufacturers.
The precision coating provides wear resistance against abrasion, erosion and corrosion on components made from ferrous and nickel-based alloys. It coats internal surfaces and offers technical and environmental advantages over hard chrome and HVOF. Independent 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.
