DOPAMINE AGONISTS FOR THE THERAPY OF COCAINE ADDICTION

Not Available Moving mechanisms for satellites as well as missile propulsion and space power require significant improvements in the temperature capabilities of lubricant materials and lubrication systems. The Wear Sciences and Coatings Group of TA&T, Inc. is pleased to propose a significant state-of-the-art advance in wide temperature range solid lubrication. Using closed field unbalanced magnetron sputtering, unique Al-Cu-Fe-Cr and Al-Co-Fe-Cr quasicrystalline coatings offer the potential for both low friction and low wear from ambient up to as high as 900¿C plus. Scratch adhesion, nanoindentation hardness, braile indentation, room and high temperature friction and wear tests will be used for comparing the physical and tribo-characteristics of the experimental films. Inconel 718 will be coated with the most promising coatings and tested under start-up and touch-down conditions indicative of foil bearings. These tests and post test analyses will provide the basis for coating refinements, foil bearing, rolling element bearing, fretting and abradable seal testing in Phase II.
