HVOF Facility Qualification at an Airline – Importance and Benefits for Landing Gear Applications

A commercial air carrier has replaced the chrome plating on line-of-sight landing gear installed on several aircraft with HVOF sprayed WC-Co-Cr coatings. Pending the results of ongoing testing and service evaluations, the carrier plans to switch to HVOF coatings on all line-of-site landing gear and possibly other structural and engine components. This paper discusses the infrastructure that will be necessary to build, qualify, and maintain a high-velocity oxyfuel spraying facility that will serve one of the largest fleets of aircraft in the world. Paper includes a German-language abstract.
