Nothing to Fret about Fretting

Fretting occurs when two materials come in contact with each other under load and are subject to a very low amplitude relative motion, often due to vibration. Usually, the amplitude of the vibration is 50 microns or less. This phenomenon occurs across a wide range of industries, and understanding this wear process, as well as the effectiveness of palliatives is important. In electronic packaging fretting can occur where two contacts mate. In aerospace applications, this process occurs where the turbine vanes dovetail to the rotor disk. In the automotive industry, this can occur in under-the-hood applications like engine mounts. A new UMT drive with a fully programmable stroke length and frequency will be used to demonstrate how materials can be tested to make sure that materials and coatings selected for these types of applications are suitable. The new drive is designed to work in a variety of application-specific environments.
