Abstract
The purpose of this project is to demonstrate the effectiveness of using a conductive, wear resistant coating to improve the lifetime and reliability of slip rings, in particular the slip ring system used in the V-22 Osprey. Acree Technologies Incorporated has developed an innovative, conductive coating that is exceptionally hard, smooth and wear resistant and has a low coefficient of friction. This coating has been shown in previous tests to improve the lifetime of surfaces in sliding contact by greater than five times. Preliminary sliding contact tests have shown that the electrical noise of a coated slip ring is less than 10 mohm, exceeding military specifications.
