THE INFLUENCE OF MECHANICAL FORCE ON CREATING PHYSICOCHEMICAL PROPERTIES GREASES

Journal Title: Tribologia - Year 2009, Vol 228, Issue 6

Abstract

The paper presents the results of investigation of the mechanical force on the mechanical and thermal stability greases. Research grease composition received was dispersed on the synthetic and mineral oils with inorganic filler. The esters and inorganic additives were created on the tribological properties. The physicochemical properties that were examination through penetration, drop point and quantity of separation oil from greases were evaluated. The influences of the mechanical force on the change of selected parameters were also investigated. It was stated that mineral grease reduces mechanical and thermal stability. The synthetic greases increased thermal and mechanical stability.<br/><br/>
