Abstract

We have constructed an instrument designed to make measurements of interfacial mechanical properties under ultra-high vacuum conditions. The device has been configured to allow two metallic surfaces to be prepared and characterized independently within a single UHV chamber. The two can then be brought into contact to allow measurements of the frictional properties of their interface. In this manner we are able to study the frictional properties of metallic surfaces modified by the presence of mono-molecular films. The instrument is described in this paper as are the results of initial measurements performed on modified tungsten surfaces. In addition we address the question of why it is that such ultra-thin films can modify the mechanical properties of surfaces brought into contact under macroscopic loads.
