Enhancing High Temperature Life Performance of Lithium-Complex Greases

摘要

Present research work focuses on the study of enhancement of the high temperature life performance of Lithium complex greases. Effect of complexing agents, base oil type and viscosity, conventional and solid additives, etc. has been studied in detail. Greases were evaluated through tribological rig FE-9 and high temperature life rig as per ASTM D 3336. A novel approach was followed by applying rheology to study apparent viscosity at subzero temperatures and comparing rheological data with tribological data obtained as per ASTM D 1092. An effort was also made to correlate rig test data with Pressure Differential Scanning Calorimetry (PDSC) study findings.
