The experimental data on correlation results of classic tribometric and polarization tribometric experiments are given. Using models of epitropic liquid crystalline layers of finite constant and infinite high viscosity a dimensional type of structural order in the investigated lubrication layer has been determined. The experimental method is based on the analysis of the plane-polarized radiation passed through the lubrication layer during the process of stationary shear flow.

Keywords: epitropic liquid crystalline layer, mesogen, lubricating materials, lubrication layer, polarizing tribometer, anisotropy, plane-polarized radiation, stationary shear, supramolecular structure, triboactive additives, birefringence
