A method for producing a metallic green compactrelates to a method for producing the green compacthaving at least one recessincluding a step of subjecting a raw material powder filled in a resin moldto cold isostatic pressing while placing a resin core materialhaving a shape corresponding to the recessat a position corresponding to the recessin the resin mold

Method for producing green compact and method for producing sintered body

A method for manufacturing a porous metal body according to the present invention includes: a surface oxidizing step of heating a titanium-containing powder in an atmosphere containing oxygen at a temperature of 250° C. or more for 30 minutes or more to provide a surface-oxidized powder; and a sintering step of depositing the surface-oxidized powder in a dry process, and sintering the surface-oxidized powder by heating it in a reduced pressure atmosphere or an inert atmosphere at a temperature of 950° C. or more.

Method for manufacturing porous metal body, and porous metal body

The titanium-based porous body according to the present invention is in a form of a sheet and contains titanium, and the titanium-based porous body has a thickness of 0.8 mm or less, a porosity of 30% to 65%, a maximum height Rz1 of one sheet surface of 30 μm or less, a ratio of a maximum height Rz2 of other sheet surface to the maximum height Rz1 of the one sheet surface (Rz2/Rz1) of 1.2 or more, and a compression deformation rate of 19% or less.

Titanium-based porous body and method for producing titanium-based porous body

A manufacturing method of a gas diffusion layer with a microporous layer includes coating a gas diffusion layer containing titanium with a precursor containing an electroconductive material, a water-repellent resin, and a polyethylene oxide, and heating the gas diffusion layer coated with the precursor to form a microporous layer containing the electroconductive material and the water-repellent resin on a surface of the gas diffusion layer. The heating atmosphere is a non-oxidation atmosphere where an oxygen concentration is no more than 0.3% by volume.
