Title:
METHOD FOR PRODUCING POROUS MEMBER
Document Type and Number:
WIPO Patent Application WO/2017/141598
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing a porous member that makes it possible to produce a member having smaller micro-gaps, to make only an outermost surface porous, and to form a porous layer on a surface while maintaining the characteristics of an unformed part of the porous layer. [Solution] A solid metal body 11 comprising a first component is brought into contact with a solid metal material 12 comprising a compound, an alloy, or a non-equilibrium alloy that simultaneously contains a second component and a third component having, respectively, a positive and a negative mixture heat with respect to the first component, then heat treatment is performed at a predetermined temperature for a predetermined length of time. Once the heat treatment causes the first component to be diffused on the metal material 12 side and the third component to be diffused on the metal body 11 side, parts other than a part mainly comprising the second component are selectively removed from the parts in which the first component and/or the second component are diffused and a member having micro-gaps is obtained.
