Molybdenum metalworking

Deep drawing and stamping. Wall reductions of as much as 20% between heat treatments have been achieved with the deep drawing process. Heating of both sheet and dies are suggested for the best results on sheets over 0.5 mm thick. Conventional equipment, tooling, and lubricants normally produce acceptable results. 

Spinning. The use of stress-relieved material and the continuous application of heat are the only precautions to observe. Otherwise, molybdenum can be routinely fabricated into a variety of shapes.

Utilisation of molybdenum disulphide generally has been increasing steadily, and it seems clear that in many areas its use has achieved technical respectibility after the exaggerated claims and complaints of the 1950 s and early 1960 s. The aviation industry has always been a leading user, but there is now a more widespread acceptance of molybdenum disulphide in various forms. Among the other industries which have accepted its use in a wide variety of applications are metalworking and railways. 

An obvious disadvantage of easy transfer is that it results in depletion of the molybdenum disulphide in the primary source, and this may be a factor in determining the life of a lubricating film. However, once a smooth transfer film has been formed on a counterface, the transfer process either diminishes considerably or ceases altogether. The problem of depletion of the source is therefore only likely to be serious in systems in which the primary source is a film in continuous or repeated contact with fresh counterface, that is a counterface which is not yet carrying a transfer film. This is most likely to arise in processes such as metalworking, where molybdenum disulphide on a tool or die may be progressively transferred to fresh metal stock.
