Method of obtaining a composite materialnnanostructured ceramic matrix and machinable bynEDM, and product obtainable by said method.n n n It allows to obtain a ceramic / semi-composite material Nanostructured and machinable conductor / metal by EDM. The starting materials are: a nanometric particle size ceramic material, a nanometric particle size semiconductor material, and a metal salt, used as a precursor to the corresponding metal. The method comprises the steps of: a) preparation of a ceramic powder / metal oxide material by calcining a dry powder obtained from a homogeneous suspension of the ceramic material and the metal precursor metal salt; b) addition to the powder resulting from the previous stage of the semiconductor material; c) grinding, homogenization, drying and sieving of the powder resulting from the previous stage; d) heat treatment in a reducing atmosphere of the powder resulting from the previous stage, and e) forming and sintering of the powder from the previous stage. |
