Preparation method of perforating charge shaped charge cover

The invention relates to the field of powder metallurgy, in particular to a preparation method of a perforating charge shaped charge cover, which comprises the following steps: preparing iron-coated tungsten powder by using pentacarbonyl iron and tungsten powder, putting the iron-coated tungsten powder into a prepared copper salt reaction solution, obtaining copper-coated tungsten composite powder from the copper salt reaction solution with the iron-coated tungsten powder, and reducing the copper-coated tungsten composite powder to obtain the perforating charge shaped charge cover. Mixing the reduced copper-coated tungsten composite powder with graphite and engine oil to obtain a mixed material; and the mixed material is taken to be subjected to spinning compression molding, and the shaped charge liner is obtained. According to the technical scheme, on the basis of the replacement principle of iron and copper, the copper-coated tungsten powder is prepared on the basis of the iron-coated tungsten powder, the c
