FUNDAMENTAL INVESTIGATION OF MOLYBDENUM DISULFIDE AS A SOLID LUBRICANT

Abstract

This report describes three months of work on an investigation of molybdenum disulfide (MoS2) as a solid lubricant. The objective, scope, and program in general are briefly reviewed. A reference powder of documented composition and particle size distribution was used for making a limited number of preliminary compression tests. The relation between specimen fracture stress, specimen specific gravity, and specimen length-to-diameter ratio was investigated and is discussed. The variations of specimen specific gravity and hardness in the longitudinal direction were also studied and the results are presented. A crack developed in the four-piece tapered sleeve of the compacting die during compact pressurization, and a new sleeve is in the fabrication stage. Fabrication and assembly of the test apparatus was completed and is being instrumented and calibrated for subsequent work.
