摘要: Abstract The effects of stainless steel powder particle size, sintering temperature and soaked time on the oxidation resistance performance foam with 3D open-cell network structure at 800 °C were mainly investigated, improvement mechanism Cr 3 C 2 was also discussed in this paper. experimental results show that improves decrease increase prolongation time, which may be due to facts fine high long can make sintered compactly oxidizable interface between air medium shrink, same open porosity decreases; addition is effective improve ability preferential formation excessive compact anti-oxidation O film existence ; however, bending strength content rising.
