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 in 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. The paper at hand presents the results of a heat treatment prior to cold forging operations on the performance of polymer, saltwax, soap and molybdenum disulfide. The zinc-phosphate + molybdenum disulfide lubrication system indicates that a heat treatment of the lubricant results in a decrease of the friction coefficient.
