Abstract : The wear of diamond draw-plates was determined as the length of Mo wire that could be drawn before the diameter of the wire had increased by 1 mu. Lubricants used were a mineral oil, castor oil with a surfactant, Li ricinoleate, and Li sterate. Fillers used were mica, graphite, and MoS2. Filler particle size was 20-40 and 120-150 mu. Without fillers, the castor oil reduced wear more effectively than the mineral oil. Li ricinoleate was superior to Li sterate. When the fillers were used alone without a carrier was 2-3 times more effective than graphite, and mica had no positive effect at all. Increasing the particle size reduced some what the protection against wear. Lubricants made of each of the 3 fillers in each of the 2 oils were all superior to the oils alone. Optimum results were obtained with 30 percent MoS2 in castor oil. The mode of action is discussed. (Author)
