摘要：
Twelve samples of diurea greases with four different types of base oils were tested for the effect of composition on film thickness in rolling elastohydrodynamic contacts. Irrespective of the grease type, the film thickness linearly increased at 25, 100 and 150 °C. However, the absolute value of the film thickness was affected by the type of the base oil as well as the temperature at which it was measured.
