Abstract<br />
Micromachines have the potential to significantly impact future weapon component<br />
designs as well as other defense, industrial, <strong>and</strong> consumer <strong>prod</strong>uct applications. For both<br />
electroplated (LIGA) <strong>and</strong> surface micromachined (SMM) structural elements, the influence <strong>of</strong><br />
processing on structure, <strong>and</strong> the resultant effects on material properties are not well understood.<br />
The behavior <strong>of</strong> dynamic interfaces in present as-fabricated microsystem materials is inadequate<br />
for most applications <strong>and</strong> the fundamental relationships between processing conditions <strong>and</strong><br />
tribological behavior in these systems are not clearly defined. We intend to develop a basic<br />
underst<strong>and</strong>ing <strong>of</strong> deformation, fracture, <strong>and</strong> surface interactions responsible for friction <strong>and</strong> wear<br />
<strong>of</strong> microelectromechanical system (<strong>MEMS</strong>) materials. This will enable needed design flexibility<br />
for these devices, as well as strengthen our underst<strong>and</strong>ing <strong>of</strong> material behavior at the nanoscale.<br />
The goal <strong>of</strong> this project is to develop new capabilities for sub-microscale mechanical <strong>and</strong><br />
tribological measurements, <strong>and</strong> to exercise these capabilities to investigate material behavior at<br />
this size scale.<br />
