Research about Obtaining Porous Sintered Multilayer Materials from Stainless Steel Powders

Article Preview

Porous samples under the form of disc tablets, 23 mm in diameter and approximately 2 mm thick, were made by freely spreading and then sintering stainless steel powder (316 L). The powder fraction used and the sintering time are the parameters that were varied in order to study their influence on the main structural characteristics. Different powder size ranges were used. The multilayer structure was obtained by freely spreading different particles size ranges -40µm and 100 -125µm in alternative layers. The narrow range (-40µm) of particles was used to obtain a thin layer (0,5mm) intended for small pores size and to maintain the permeability of samples in acceptable limits. The sintered structure was investigated by electron microscopy and mercury porosimetry.
