The theoretical premise of the discussed work [1] is generalization of “stationary nonequilibrium thermodynamic states” to tribological systems. Such a state characterizes a “discontinuous” thermodynamic system with minimum entropy production. It is satisfied, mathematically at least, when the phenomenological thermodynamic coefficients being “identically” constant [2]. The discusser argues that for such a condition to take place, within the context of the tribosystem considered, the thermal storage term expressed in Eq. (6) of the discussed paper has to be stated in terms of the constant volume specific heat Cv, (instead of the specific heat at constant pressure Cp used). Thus, the first entropy contribution is rewritten as
$Sfo 1=(1Tflash−1Tbulk) Qo = mo ∫TflashTbulkCvT dT$

It follows that...
