Substantiation of optical criterions of thermal-oxidative stability of lubricating

Research results of criteria of thermal-oxidative stability determined by different combinations of coefficient of absorption of light quantity and optical density with coefficient of evaporation and kinematic viscosity of oxygenated oil are presented. It is shown that the amount of optical density and the coefficient of evaporation divided by coefficient of relative viscosity are the most effective criteria of thermal-oxidative stability of lubricating oils described by second order polynomial with a high correlation coefficient. © Published under licence by IOP Publishing Ltd
