ABSTRACT:
Metal fibers obtained by the bundled drawing of a composite bundle of metal wires embedded in a metal matrix followed by the electrolytic removal of the matrix so that the surface layers of the fibers contain only a negligible amount (.ltoreq.0.2% at) of the matrix metal. Furthermore, a description is given of a process and an apparatus for the continuous electrolytic removal of the matrix material. Thereby, the composite bundle acts as an anode. Stainless steel fibers according to the invention have an average Cr/Cr+Fe+Ni content at their surface between 1% and 15%.
