Abstract
Static friction is a phenomenon we may mainly consider as
related to frictional joints within static mechanics. The
step from static friction to tribological phenomena is,
however, rather short, since at the onset of sliding in a
mechanical contact, the static friction determines the
initial resistance against motion. Static friction
furthermore plays a role in contacts subjected to
traction and fretting. Although being a phenomenon of
short duration, the tribological phenomena during the
transition from static friction to sliding friction may
be of great importance for the operational life of the
contact surfaces, particularly if the procedure is
repeated for a sufficient number of times. The present
paper describes the principles of static friction
measurements, details of the employed static friction
tribometer and the results of measurements with
unlubricated and lubricated sliding couples consisting of
steel against uncoated and coated cast iron.
