Abstract (en)

Biological oils and greases of plant and animal origin are used as environment friendly bio-degradable lubricants. Fatty lard, its greases with sodium and lithium soap thickeners and lubricant additives was used for tribological investigations. Tribological tests with 4 balls testing machine at 150 N and the drop point measurements were performed. Research results show higher lubrication efficiency of lard, its greases with sodium and lithium thickeners and lubricant additives comparing to commercial high-quality grease. The use of Lubrizol additives in lard greases significantly decreases the friction torque and the wear scar diameter of test balls. The investigation show that homogenisation of natrium soap greases can significantly increase wear resistance of friction pairs.
