There are many factors which control the porosity of the final object during preparation of
porous copper compact using PM (powder metallurgy) technique. The amount of filler
material, its type, sintering temperature, sintering time and the pressure of compaction were
recognized as the most important parameters. In this investigation, naphthalene was used
as filler material during porous copper preparation. Also, the correlation between these
parameters and the porosity degree of the final object was developed with the aid of 2N …

… In this investigation, naphthalene was used as filler material during porous copper preparation.
Also, the … In the present work the experimental design method (2N factorial design) used to
carry out a relationship between the different parameters affecting the porosity degree of the
porous copper compacts. The factors controlling the porosity degree are sintering temperature,
sintering time, compaction pressure and amount of naphthalene. Since the number of …
