Preparation of Micron Porous Copper by Vacuum Heat Treatment

Graphical Abstract

Abstract

Abstract

Micron porous copper was prepared by vacuum heat treatment of Cu₇₅Zn₂₅,Cu₅₀Zn₅₀and Cu₂₅Zn₇₅alloys at 450℃,500℃and 550℃.XRD,SEM and EDS were used to analyze the prepared porous copper,and the effects of temperature and composition on the pore morphology after vacuum heat treatment were studied.The results show that the pore size of porous copper prepared by vacuum heat treatment is 0.5-8.0μm.The pore diameter increases with the increase of temperature.With the increase of Zn content in Cu-Zn alloy,it is easier to form porous structure and larger pore size.
