Abstract The nanoporous arrays on the surface of NiAl-W eutectic alloy were obtained through a combined process of directional solidification and selective dissolution. The spacing and diameter of rod-like tungsten phases in the NiAl-W pseudobinary eutectic both can be tuned through the selection of growth rates during directional solidification. Thus, the spacing and porous diameter of porous array on the surface of NiAl matrix could be also adjusted after removing rod-like W phase through the electrochemical selective dissolution. Because of the limitation of the pore size, the deepening of the depth of etching porous zone has been suffered an enormous hindrance after etching of 2—3 hours at the potential of 0.5 V.

Key words： rod-like eutectic nanoporous array NiAl-W directional solidification selective dissolution
