A cellular structure is produced by electroplating iron on to a conductive porous substrate, e.g. an agglomerate of fibres such as felted material, natural sponge or synthetic resinous foam such as polyurethane foam, and thereafter alloying the foam by contacting it at elevated temperature with an alloying componant or precursor thereof. The substrate may be inherently conductive, i.e. by inclusion of a conductive additive therein, or maybe providedwith a conductive coating, e.g. by chemical deposition. The alloying element may be C; Si; N; Be; Zn; Cd; B; Al; Ti; Zr; Sn; Cr; Mo; W; Co or Ni. Various methods of alloying the iron foam are described. The resulting structure may be heated to ash out the substrate.</p> |
