Fabrication of the lamellar NiAl nanochannel by selective phase dissolution of NiAl–Cr(Mo) eutectic alloy
Source abstract
Abstract
Abstract A novel lamellar NiAl nanochannel with NiAl lamellae and nanochannels was fabricated from directionally solidified NiAl–Cr(Mo) eutectic alloy by selective phase dissolution. The optimum potential for the selective dissolution was at 1.14 VSHE. Results revealed that the Cr(Mo) phase in the NiAl–Cr(Mo) eutectic was removed completely, and the lamellar nanochannel was revealed during the selective dissolution. The width of the nanochannel was 620 nm, and the depth approached 83.6 μm; both can be tuned by controlling the growth rate and dissolution time. These highly oriented NiAl architectures with narrow nanochannels can be used to fabricate multilayered devices/capacitors.
