This research corresponds to the first experimental validations of the mechanochemical friction (MQf) for the simple and direct verified calculation of the s-LCC: Scuffing Load Carrying Capacity, which are interacting the following: base material, superficial treatment, lubricant additive and operation conditions. The good obtained correlation confirms the true non-equilibrium irreversible thermodynamic nature of the wrongly so called friction "coefficient". In other words, it is confirmed that the empirical on-site friction, or mechanochemical friction, based on the notion of the 3rd tribological body, is-NOT- a thermally dominated phenomenon. With this new mechanochemical paradigm, it would not be necessary to extend beyond a few minutes (even seconds), the s-LCC projection technique for MQf. The new method is on-site applicable (to clients). © 2012 Universidad Central de Venezuela.
