The effect of vibrational energy on the densification and interparticle friction of metal powders
thesis
posted on 2018-11-08, 17:16 authored by Thomas P. FisherThe production of engineering components by the
process of metal powder compaction and sintering is a
rapidly expanding process. The filling of all parts of
the die cavity to uniform densification prior to compaction
is an essential part of the process if compacts of even density free from spalling are to be obtained.
The research has the main objectives of showing how
the variable parameters of vibrational energy will affect
the densification of a range of powders having a wide
variation of characteristics, into dies of restrictive
sections. The mechanism of densification is essentially
by reduction of interparticle friction and a shear cell
has been devised to measure interparticle friction under
various conditions of vibrational energy. [Continues.]
