Abstract: | Boric acid and borax, which are used as antiscoring additives to an environmentally friendly glycerin-based lubricant, have been studied. It is shown that the adsorption of borax obeys the Langmuir isotherm. The equilibrium constants of the adsorption of the additives and the energy of the adsorption are estimated. It has been found that borax is a more effective antiscoring additive than boric acid. For borax used as the additive, the dependence of the coefficient of friction on the load applied to a friction unit is studied and interpreted. |
