The invention relates to a method for preparing micrometer porous metal copper blocks by dealloying of copper-ferrum alloy. According to the method, plasma is adopted to activate and sinter copper-ferrum alloy, and then ferrum in the alloy is selectively corroded by utilizing a chemical dealloying method, thus obtaining porous copper blocks with high-strength micrometer apertures. According to the invention, by utilizing the characteristic that the copper-ferrum inter-atom diffusing capacity can be greatly reduced by a quick sintering process of hard miscibility of copper-ferrum alloy, which is lower than the melting point of ferrum, the dimension of a ferrous phase after sintering approaches to the particle size of micron-size material powder, so as to prepare the copper-ferrum bi-continuous three-dimensional net structured copper-ferrum alloy; the particle size of adopted copper powder is slightly smaller than that of ferrous powder, so as to form a structure that copper particles wrap ferrous particles, thus being favorable for ensuring the uniformity of aperture after corrosion; the pore structures of the porous metal copper blocks are regulated and controlled by changing the ferrous powder content and the particle size distribution; according to the process, the high-strength micrometer porous copper blocks with uniform pore distribution and adjustable pore size and porosity can be obtained; and the method has the advantages of being simple in process, low in cost and strong in practicability.
