Abstract:
In this article we presented the study of the rheological behavior of two oils used in biodegradable lubricants. Depending on the shear rate and the shear stress, it is found that olive oil has a greater slope than coconut oil. If the viscosity dependence of the shear stress or shear rate is shown graphically, it is found that the viscosity decreases exponentially with both the shear speed and shear stress. The coconut oil and oil olive have investigated using a Haake VT 550 Viscotester developing shear rates ranging between 3 and 120 s-1 and measuring viscosities from 104 to 106 mPa•s when the HV1 viscosity sensor is used. The temperature ranged between 40 and 100oC and the measurements were made from 10 to 10oC. The accuracy of the temperature was ± 0.1oC.
