Research Topics


A new class of thin film materials, diamond-like nanocomposites (DLN), has developed. These materials have properties that make them excellent candidates for coating sliding electrical contacts. In the recently completed Phase I program, the unique properties of the coatings were demonstrated. In the Phase II program, we propose to coat coupons and motor parts. Coating motor parts is expected to result in significantly higher motor performance and lower maintenance. A series of coating depositions will be performed to optimize the desposition parameters for the specific substrate materials. We propose to study tribological properties of the coatings in collaboration with Oak Ridge National Lab. Coatings will also be tested through simulations and in actual motors. We will work with MET, a motor manufacturer, who will supply motor parts and test the performance of motors containing DLN coated components.
