Embodiment

[0089] As examples of the present invention, (1) samples (Nos. 1 to 12) of porous metal bodies using a raw material for porous metal bodies made of aluminum steel wire rods and (2) samples formed by cutting Samples (No. 13-15) of the metal porous body of the raw material for the aluminum porous metal body. Table 1 and Table 2 show conditions such as the size of each blank for the porous metal body and the size of the porous metal body.

[0090] Each porous metal body passes through the axial direction of the coils of the blanks for the porous metal body alternately arranged in the longitudinal direction and the transverse direction (refer to Figure 10 ) to impart isotropy, and formed in the size of length 50 mm x width 50 mm x height 30 mm. The cross-sectional shape (cross section) of the billets (wires) for porous metal bodies made of steel wire rods for samples Nos. 1 to 12 is circular, and for the porous metal bodies formed by cutting processing for samples Nos. The cros...

Abstract

A material for a metal porous body wherein a wire rod comprising a metal material which has excellent thermal conductivity and can be joined by sintering forms a coil shape that is wound in a helicalfashion, the average wire diameter Dw of the wire rod is 0.05 mm to 2.00 mm, the average coil outer diameter Dc is 0.5 mm to 10.0 mm, the coil length L is 1 mm to 20 mm, and the number of windings N is 1 to 10. A metal porous body having a plurality of pores is formed by combining and sintering a plurality of the materials for a metal porous body, and the porosity of this metal porous body can easily be controlled.

Description

technical field [0001] The present invention relates to a blank for a porous metal body and a porous metal body for producing a porous metal body having a plurality of pores. [0002] This application claims priority based on Japanese Patent Application No. 2018-056167 filed on March 23, 2018, and uses the content thereof here. Background technique [0003] In order to produce a porous metal body having isotropy, anisotropy or gradient properties, various methods have been proposed. [0004] For example, Patent Document 1 discloses a sintered molded body having a porous structure formed by sintering randomly distributed stainless steel fibers having an average equivalent diameter of 5 to 50 μm and an average length of 30 to 2000 times the diameter. A sintered molded body having such random distribution of fibers usually becomes an isotropic metal porous body. [0005] Patent Document 2 discloses a porous energy absorbing member obtained by sintering metal fibers oriented i...
