Gansheimer and Wessely ° examined the value of several different lubricants for lubrication of screw or bolt threads. Some of the torque and friction values they 

One other area in which the use of molybdenum disulphide may be undesirable for pre-assembly or anti-seize use is when nickel alloys are used in critical applications, especially at high temperatures. Such alloys are extensively used in aviation gas turbine engines, and there have been cases in which serious failures of gas turbines have been attributed to the effect of molybdenum disulphide-based lubricants on high-temperature components Provided these two hazards are kept in mind, molybdenum disulphide dispersions and pastes are of great value as antiseize compounds and as assembly aids. 

Pastes and dispersions have also been recommended for running-in ( breaking equipment after assembly, but there are limitations on the extent to which this 

High-solids dispersions and pastes are used in many different forming operations, especially in cold or warm forming of steel by drawing, pressing or extrusion. The critical problem in such operations is that high proportions of freshly-
