Tohoku Univ. Technology：Open type Nanoporous body, surface treatment, composite：T10-043_T22-030
There are many examples such as stainless steel (austenitic and ferritic), nitinol, Si, C, Fe, W, Ti, Cr, Zr, Nb, Mo, Ta, Fe-Cr-Co-Ni-V high entropy alloy, Ni-Mo alloy, Fe-Al alloy, etc.! Depending on the application, magnesium and iron composites can also be made!
Conventionally, for porous metals (Nano-microporous metals) having micropores of nano or micrometer size, a dealloying (deconditioning) method has been used to obtain porous bodies by corrosion-removing only noble metals from alloys of noble and noble metals in aqueous solution. However, there is a problem that the target metals are limited in that it is possible to fabricate nano-microporous metals only in noble metals and their alloys with respect to the standard hydrogen electrode potential. The present invention can easily fabricate nano-microporous bodies in vulgar metals and their alloys that could not be fabricated in principle by conventional methods. As one specific example, the nano-porous bodies were successfully fabricated in pure metals such as titanium, niobium, and molybdenum, alloys such as beta titanium and stainless steel (austenitic and ferritic), and carbon.
