THE TRIBOLOGICAL PROPERTIES OF LUBRICATING GREASES BASED ON RENEWABLE OILS
Journal Title: Tribologia - Year 2016, Vol 266, Issue 2
Abstract
The paper discusses the influence of vegetable oil basis on lubricating properties of their selected compositions. Four vegetable oils were used for production of lubricating greases: rapeseed, sunflower, soybean, and castor, all thickened with modified silica of Aerosil® type. The tribological properties of lubricating greases based on vegetable oils were investigated. On their basis, the most beneficial compositions were selected. The tribological properties of greases were estimated via measurements of limiting load of wear (Goz/40), welding load (Pz), scuffing load (Pt), limiting load of scuffing (Poz), and the limiting pressure of seizure (Poz). Based on the obtained results, it may be concluded that the best antiwear properties were shown by the lubricating compositions based on rapeseed oil, whereas the best antiscuffing properties have compositions using castor oil as a disperse phase.<br/><br/>
