摘要	A Ti-48Al-6Nb porous microfiltration coating was fabricated by cold gas spraying (CGS) followed by reactive sintering. The porous coating possesses a porosity of 20.0% and interconnected pore structure. The skeletons in the coating were consisted of typical gamma-TiAl/alpha(2)-Ti3Al fully lamellar microstructure, and firmly bonded with substrate. Uniform pores in the range of 0.5-3 mu m were formed, attributing to the diffusion reactions and skeletons growth during the reactive sintering process. The bending strength and gas permeability of the supported coating with a thickness of 604.4 mu m, are 89.33 MPa and 5.39 x 10(-13) m(2), respectively. The porous coating has high permeability and sufficient strength for microfiltration applications in kinds of extreme environments. (C) 2012 Elsevier B.V. All rights reserved.
