Title:
金属多孔体とその製造方法
Document Type and Number:
Japanese Patent JP4117740
Kind Code:
B2
Abstract:
A porous metal body has protrusions, whereby each protrusion is an angular pyramid where the base surface on the upper side is smaller than that on the lower side. A polygonal opening is pierced in the base of the upper side of each protrusion, from the upper side base to the lower side base. The vertical distance (d) between the base of the upper side recto and verso, and the height (e) of the pierced part is such that 0.3e/d0.9 A porous metal body (1) has protrusions (3) shaped in recto and verso in a metal sheet so they alternate on each side. The porous metallic body has a large number of independent openings, made of protrusions formed in recto and verso in a metal sheet so they alternate, each protrusion in the form of a rhombic pyramid where the base surface on the upper side is less than the base surface on the lower side of the protrusion. The opening is rhomboid in plane and is pierced from the base of the upper side towards the base of the lower side formed in the base of the upper side of each protrusion. The opening has a small concave part (9) in the form of a rhomboid pyramid in the center of the upper base side, and an opening cut (10) towards the four corners of the upper side base in the center of the little concave part so it is shaped with petals opening downwards. One of the two diagonals of the rhomboid in the protrusion extends in the same direction as the longer side of the porous metal body. Alternatively the protrusions are triangular pyramids with three-cornered cuts in the top. The metal sheet is 10-50 microns thick (h), and with the protrusions (d) is 0.06-1.2 mm thick. The mass per unit area of the metal sheet is 50-450 g/m2. The angle (approximately q) formed by a pierced part towards the base of the protrusion and the flat base of the upper side is 0-90 degrees. The metal body is made by pressing between two rollers.
