摘要： A method of manufacturing an electrode sheet for capacitors comprises the step of forming a sprayed layer of an A1-valve action metal alloy on at least one surface of an aluminum foil (2) by thermally spraying A1-valve action metal alloy powder on the surface of the aluminum foil. At the time of the spraying, a porosity content rate of the sprayed layer (3) is controlled to 20 vol% or less by melting at least a matrix A1 phase of the alloy. The electrode sheet for capacitors manufactured by the method can decrease the porosity content rate of the sprayed layer, which in turn can secure less leakage current and larger capacitance.

摘要： A sheet for capacitor electrodes includes an aluminum core sheet 3 and a porous layer 4 formed on at least one surface of the core sheet 3. The porous layer 4 includes an intermetallic compound made of one or more valve metals selected from the group consisting of Ti, Zr, Nb, Hf and Ta, and Al. The porous layer is constituted such that particles of the intermetallic compound are fixed in solid solution in which the one or more valve metals are dissolved in Al. Atomized molten alloy including valve metal and Al is sprayed approximately downward, and an inert gas flow 19 is injected against the spray flow to generate a branched spray flow 16 of the atomized alloy from the spray flow 15. The branched spray flow 16 is jetted against a foil-like core material 3 and then rolled. According to the sheet for capacitor electrodes, larger capacitance can be obtained and the sheet is excellent in bent-resistant performance.

摘要： A forging apparatus 1A includes a swaging apparatus 2 equipped with a fixing die 10, a guide 20 having an insertion passage 22 for inserting and holding a bar-shaped raw material 5 in a buckling preventing state, and a punch 30. The raw material 5 is fixed to the fixing die 10 with the one end portion of the raw material protruded. The one end portion of the raw material 5 is inserted into the insertion passage 22 of the guide 20. Thereafter, while pressing the raw material 5 with the punch 30 in the axial direction, in a state in which an entire peripheral surface of the exposed portion 8 of the raw material 5 exposed between the guide 20 and the fixing die 10 is not restrained, the guide 20 is moved in a direction opposite to the moving direction of the punch 30 so that a length of the exposed portion 8 of the raw material 5 becomes a budding limit length or less at a cross-sectional area of the exposed portion 8 of the raw material 5. Thus, the one end portion of the raw material 5 is subjected to swaging processing.
