SBIR-STTR Award

The technology resulting from this effort will provide a comprehensive thermomechanical/ impact wear model. This integrated model will consider the developed thermal energy due to sliding friction and impact loading of the wear surface. In addition to the development of the theoretical model, a unique bench wear fixture will be designed, fabricated, and validated. This fixture will provide variable input conditions for validating the thermomechanical/impact wear model.

The technology resulting from this effort will provide a theoretical wear model which, although focused on predicting slipper surface wear associated with Air Force high-speed sleds, can be utilized with appropriate input modifications to predict wear in a range of mechanical devices where high-pressure and high-velocity surfaces are utilized. In addition, a high-speed, high-pressure pin-on-disk wear device will be fabricated, assembled, and validated for use in validating the basic wear model and for evaluating tribological material and/or coating systems.
