LUBRICATING PROPERTIES OF ALGAE OIL IN STEEL–STEEL TRIBOSYSTEM
Journal Title: Tribologia - Year 2013, Vol 251, Issue 5
Abstract
The physic-chemical and lubricating properties oil of obtained from algae are studied. It was found that important, from tribological point of view, physico-chemical properties of algae oil are similar to those of rapeseed oil. Both oils have a similar density as well as kinematic and dynamic viscosity at 100°C. Algae oil has a slightly lower kinematic and dynamic viscosity at temperatures below 60°C and a slightly higher viscosity index. The biggest difference between the oils was found in the susceptibility to thermal oxidation – algae oil is less resistant to thermal oxidation from rapeseed oil. Algae oil has slightly worse lubricating properties in steel-steel tribosystems, evaluated on the basis of the value of limiting load of wear (Goz) and scuffing load (Pt) . However, the lubricating properties of algae oil are sufficiently similar to rapeseed oil. Therefore, it can be used as an alternative to rapeseed oil in the ecological lubricants.
