In this paper the transition from mild wear to severe wear of lubricated, concentrated contacts is dealt with. It is suggested that this transition is thermally induced. The transition from a mild wear to severe adhesive wear occurs when more then 10% of the surface transcends a predefined, critical temperature. A method for determining this critical temperature is presented. Using a BIM based numerical model including the local implementation of Archard’s wear law, for the contact pressure and temperature the transition diagram for a model system is calculated and validated by experiments. The transition predicted by numerical calculations is in very good agreement with the experimental determined transition.
