AJ 106-2 – Molybdenum Disulfide – Ford Method
AJ 106-2 Molybdenum Disulfide, Lithium Soap and Polyethylene in Greases
Molybdenum disulfide (MoS2) in grease formulations helps to improve lubricity, particularly in high temperature-extreme pressure operations such as in constant velocity joints (CVJs) and ball joints. The proper level of MoS2 is important in greases. Insufficient MoS2, may limit lubricity of the grease. Excessive MoS2, may increase galvanic corrosion and wear, particularly in wet or oxidizing environments. This test determines the level of molybdenum disulfide in greases.
The grease solids are isolated through a Soxhlet extraction. The solids are then processed through a series of chemical and physical processes and a final gravimetric determination is made to determine the percent of molybdenum disulfide in the sample.
