采用粉末冶金法在不同温度下合成了具有不同相骨架的Ti-48 Al-6 Nb多孔合金。在700°C下获得的TiAl 3骨架被腐蚀产物覆盖，骨架断裂导致孔隙塌陷。在900°C时，TiAl骨架形成明显的腐蚀坑，孔径增大。在1350°C下获得的Ti 3Al/TiAl骨架具有最好的耐酸性腐蚀性能，质量损失最小，为1.853 mg m-2。只有出现完全层状结构时，孔结构和孔径才保持稳定。此外，Nb 2Al相呈现出更好的电阻比NbAl 3在骨架有助于耐酸性的多孔合金。
Ti–48Al–6Nb porous alloys with different phase skeletons were synthesised by powder metallurgy at different temperatures. TiAl3 skeletons achieved at 700°C were covered by corrosion products and skeletons fractures led to pores collapse. TiAl skeletons were synthesised at 900°C with obvious corrosion pits and pore diameter increasing. And Ti3Al/TiAl skeletons achieved at 1350°C exhibit the best acid corrosion resistance with the least mass loss of 1.853 mg m–2. Skeletons and pore diameters remained stable just with fully lamellar structures emerged. In addition, Nb2Al phases presented better resistance than NbAl3 in the skeletons contributing to acid corrosion resistance of the porous alloys.
