Technology Assessment and Transfer will demonstrate the potential of novel, low friction and low wear coatings that are capable of providing long term durability for air cycle machine foil bearings. A systematic approach with a high probability of success includes the following: unique low friction, wear resistant alloys and lubricating ceramic composites, magnetron sputtering, the ideal method for depositing thin, adherent single and multilayer coatings on high temperature alloy substrates; comprehensive characterization methods - XRD, SEM, EDS to optimize coating chemistry and microstructure; wide temperature range tests of friction and wear including start-stop tests to determine and compare the capabilities and potential of the experimental foil and journal coatings for enhanced performance.
