Kurzbeschreibung (Abstract)
Cold forging operations are subject to high tribological loads. In order to enable a reliable forging process, lubricants have to be chosen with respect to the occurring loads. However, it is known that well established lubricants can increase the surface roughness of a specimen as a consequence of the forming. On the other hand, zinc-phosphate + molybdenum disulfide which is known to create a smooth specimen surface often shows higher friction coefficients. Therefore, a sound lubrication is of special interest for near net-shape operations. The paper at hand presents the results of a heat treatment prior to cold forging operations on the performance of lubricants. The zinc-phosphate + molybdenum disulfide lubrication system indicates that a heat treatment of the lubricant results in a decrease of the friction coefficient. Tests on the Sliding Compression Test as well as a standard rod extrusion process were carried out in this investigation.
