VL - 34 IS - 1-2 SE - Peer reviewed articles DO - UR - https://journal.fi/tribologia/article/view/58520 SP - AB - <p>Static friction is a phenomenon we may mainly consider as related to frictional joints within static<br>mechanics. The step from static friction to tribological phenomena is, however, rather short, since at the<br>onset of sliding in a mechanical contact, the static friction determines the initial resistance against motion.<br>Static friction furthermore plays a role in contacts subjected to traction and fretting. Although being a<br>phenomenon of short duration, the tribological phenomena during the transition from static friction to sliding<br>friction may be of great importance for the operational life of the contact surfaces, particularly if the<br>procedure is repeated for a sufficient number of times.<br><br>The present paper describes the principles of static friction measurements, details of the employed static<br>friction tribometer and the results of measurements with unlubricated and lubricated sliding couples<br>consisting of steel against uncoated and coated cast iron.</p> ER -
