| Abstract | More and more attentions have been paid to porous stainless steel, as the excellent performance in the physical, chemical and mechanical properties, in the field of solid oxide fuel cell, medical drug for implantable devices and so on. In this work, a new method called physical vacuum dealloying has been applied to produce porous stainless steel. Firstly, 316L-50Mn initial alloy was successfully melted by vacuum induction furnace, then the porous stainless steel was developed by 316L-50Mn after heat treatment in vacuum environment in this experiment. SEM, EDS and XRD were used to analyze the porous stainless steel made by physical vacuum dealloying method. Meanwhile, the effects of temperature and time on the formation, development and morphology of pores during the dealloying process were also studied. The results show that it was effective to produce porous stainless steel by physical vacuum dealloying method. The porosity of micro pores in porous stainless steel is 30%similar to 60%, with 0.5 similar to 3 mu m pore size, and the 15 similar to 60 mm thickness. The temperature mainly affects the hole formation and development by influencing the evaporation and bulk diffusion rate of Mn element, and time plays a major role in the thickness of the porous layer in the process of preparing porous stainless steel. |
