Parker Hannifin Corporation, Aircraft Wheel
The V-22 is a fixed-wing plane with rotors that tilt so the aircraft can take off and land like a helicopter. A tiltrotor combines the speed, range and fuel efficiency normally associated with turboprop aircraft with the vertical take-off/landing and hover capabilities of helicopters. The tiltrotor aircraft represents a major technological breakthrough in aviation that meets
The tiltrotor brake pad and system must stand some of the harshest design criteria faced for an aircraft including hold and takeoff in support of mission operations and maneuvers on aircraft carriers and assault ships. The brake material must stand up to highly resistant wear, heat and fracture specifications and have a very high and uniform friction coefficient across ranges of operation.
The Challenge: Develop a
The Pyrogenics Group worked closely with Parker Hannifin in developing a special SiC coating that satisfied the quality, performance, and schedule requirements set by the mission planners. This

Case 2 – Pyrolytic Graphite Provides Optimum Erosion in
A leading electronics manufacturer of Metal Organic Chemical Vapor Deposition (
The Challenge: Test materials to determine the best selection for new resistance to ammonium offering material stability and consistent long life.
The manufacturer undertook a detailed duration test under temperature (800 °C) for 40 hours with GaN cleaning media under
The results indicated that Pyroid® pyrolytic graphite provided the most erosion resistance of all the materials (2.5X times that of CVD SiC and 8X greater than SiC coated graphite).
