Method of manufacturing a porous metal sheet having pores forming a pattern

摘要

A method of manufacturing a porous metal sheet having pores forming a pattern, comprising the steps of supplying metal powders to a peripheral surface of at least one pattern roller (1) of a pair of rollers (1, 2), on which a pattern consisting of a large number of concavities (1a) is formed; dropping metal powders to the concavities and accumulating metal powders on the peripheral surface of the pattern roller except the concavities; and rolling directly the metal powders accumulated on the peripheral surface of the pattern roller by rotating a pair of the rollers. It is preferable to laminate porous metal sheets or solid metal sheets manufactured by a method other than the above-described method on the metal sheet manufactured by the above-described method.
