Airbus to test chrome coating replacement

Airbus has agreed to start approval testing for a new tungsten carbide-based coating developed by the UK’s Hardide Coatings (Hall 4 Stand E20) as a replacement for chrome coatings. The Airbus trials will last three years. It is the eighth aerospace manufacturer to test the new coating, which is already in use in harsh environments in the oil and gas exploration sector.

The tungsten carbide coating promises excellent wear resistance against abrasion, erosion and corrosion on components made from ferrous and nickel-based alloys. It coats internal surfaces and, according to its developer, offers significant technical and environmental advantages over hard chrome. Independent testing has shown that the new Hardide coating will last 12 times as long as hard chrome.
