The dry wear profile of cam shaft

In this study, the variation of the wear mechanism and the worn surface profile of the cam shaft were investigated under the dry wear conditions. The samples which were made of AISI 1040 were hardened by induction. The counter body material was AISI 1020 borided steel. The wear was determined as weight losses of the samples as a function of wear test duration and loads. The variation of camshaft profile was captured by a level sensor during the wear. The profile variation was continuously monitored on the computer screen throughout the tests. It was found that the wear mechanisms of the cam surface change along the contact surface. The maximum wear value was obtained just to cam tip.
