Abstract

  Porous nickel with cylindrical pores was fabricated by unidirectional solidification in a mixture gas of hydrogen and argon. The pore size is significantly affected by the addition of NiO powder. The diameter and length of the pores decrease by the addition of NiO. The number of pores increases with increasing amount of NiO powder. The pore diameter decreases with decreasing NiO particle size. It is concluded that NiO powder can serve as nucleation sites for the pore formation in the process of the solidification.<br>
