Abstract The aim of this work is to develop a porous Ni-Cr-Fe alloy with pore size gradient and application potential as filtration membrane. The porous Ni-Cr-Fe alloys supports were prepared by reactive powder synthesis method, whose principle is partial diffusion during the solid phase sintering process. And then the mixture of ultrafine Ni, Cr, Fe powders were coated on the surface of Ni-Cr-Fe alloys supports by artificial brushing, which helped to form fine Ni-Cr-Fe alloys dense layers. Subsequently the homogeneous porous Ni-Cr-Fe alloys with pore size gradient structures were achieved through a vacuum sintering process. The morphology of surface and cross-section of the pore size gradient structures were cha-racterized by SEM. The phases of the alloys were characterized by XRD and EDX. The results confirmed that the prepared homogeneous pore-size-graded porous Ni-Cr-Fe alloys membrane is complete, without obvious defects and well combined with the support in a metallurgical bridging manner. With the increase of the membrane thickness, the air permeability will decrease. When the thickness of transition layer is 80 μm and the thickness of surface film is 30 μm, the maximum pore diameter is 6 μm, the air permeability is 936 m³·m^-2·h^-1·kPa^-1, the air permeability decreases by 22.64%. In the same thickness of the membrane, when the filtration precision is required, the decline rate of the air permeability of second order pore-size-graded porous Ni-Cr-Fe alloys is smaller than first order pore-size-graded porous Ni-Cr-Fe alloys. The intermediate layers play a key role in pore-size-graded porous structures. The pore-size-gradient structure of the membrane truly achieves simultaneously both high filtering accuracy and larger flux.
