STUDY OF BRONZE POROUS ALLOY Cu-Sn WORKED OUT BY METALLUGY OF THE POWDERS

Porous bronzes take popularity in various fields of technology. Their development is based on the metallurgy of powders. The samples, in the present study, are worked out by pressure sintering pressure. We used various techniques of characterization: density, hardness, optical and electronic microscopy and diffraction of x-rays. We showed that in the temperature and pressure range or field swept the density believes linearly with these two parameters. The secondary phase was identified. By microscopy, we proved that the structure is not homogeneous.
