Abstract
Porous sample were fabricated by sintering of bronze ( Cu Sn10) with different particle size range. The paper investigates the influence of the particle size distribution, temperature and sintering time on the structural characteristics (porosity, pore size, dimensional changes) of the porous parts studied. A porous structure with small-sized pores and a uniform distribution of the pore sizes is obtained in conditions of a narrow range of particle size distribution, small size of the powder particles and optimal sintering parameters.
