Abstract

Metal hollow spheres are successfully used for manufacturing of cells and porosities in the CELLULAR STRUCTURES and metallic foams that important production methods of them are based on POWDER METALLURGY. In this paper, steel hollow spheres are produced by POWDER METALLURGY method and polystyrene beads are used as substrate materials. Polystyrene beads are separated from a polystyrene block and sorted by sieving. Then, mixture of sodium silicate, as binder, and iron powder was sprayed on prepared beads. After drying, a thin layer of iron powder was covered polystyrene beads. Finally, two different heat treatment processes to produce high strength steel hollow spheres was undertaken. These processes are involving the pyrolysis of polystyrene beads and sintering process. For shell thickness measurements, determination of porosity content and flaws evaluation, shell section of hollow spheres were studied by optical microscopy. Produced HOLLOW STEEL SPHEREs are nearly uniform thickness in shell. Size of iron powder particles, cupper content and type of coating of iron powder are strongly affected on shell thickness, porosity percent and shell flaws.
