We thank Dr. Abdel-Aal for his comments and discussion. Our intention was the description of temperature, topography, and the wear behavior in quite different tribological systems by known models. Such models provide the opportunity for the construction of pa·v diagrams as a helpful tool to determine transition lines which mark the change of wear mechanisms or the beginning of tribofailure. In order to establish meaningful pa·v diagrams, the determination of the temperature in the region of contact is essential. For the determination of this temperature, the dependency of the respective material properties on the temperature was explicitly considered. Therefore, thermal properties and their variation were implicitly linked to wear damage and the strength of the respective material [1].

In addition, for the quantitative wear description in a pa·v diagram, the wear coefficient or the reciprocal shear energy density must...
