  • Economy in Car-making - Powder Metallurgy
    . This treatment removes most of the oxygen and carbon from the powder, it becomes grey instead of black and, above all, it becomes soft, which makes it compressible and thus suitable for die compaction. During annealing, the powder forms a quite hard cake, which has to be disintegrated. Finally, the powder
  • Fluoroplastic Technical Terms and Definitions
    but, in some cases, it can be a serious disadvantage as it results in high, static charge, build up: this in turn can result in dust pick-up and/or spark generation. The established way of improving conductivity is by adding a conductive filler such as, a high structure, carbon black. The addition
