Abstract [en]

In order to investigate friction behaviour of powder during the compaction, die pressing is often used. Compaction is a complicated process and direct and continuous measurement of coefficient of friction is not easy. The coefficient of friction varies due to changes in the pressure distributions during compaction. In this paper a new device for measuring the coefficient of friction between metal powder particles in contact with the die-wall during compaction is presented. The device is able to measure the friction coefficient between the powder particles and the die-wall directly and continuously. Sliding velocity, compaction velocity, normal load and temperature can be monitored and controlled. Measurement of the coefficient of friction at low densities is one of the advantages, and possible application, of this apparatus.
