Study on rheological and tribological behaviour of rapeseed oil

Résumé

In this paper, modern methods for investigating a characterization of the rapeseed oil are presented. This oil has good characteristics and therefore can be used for manufacturing biodegradable lubricant. It was mathematically determined the dependency between wear scar diameter, sliding speed and load. At the same time, the variation of dynamic viscosity with temperature and shear rate was determined. The dependency between the main characteristics of the rapeseed oil, by using an original evaluation technique, was determined.
