造孔剂含量对粉末冶金不锈钢多孔材料孔隙率和抗压强度的影响

Effect of Pore-Forming Material Contents on Porosity and Compressive Strength of Stainless Steel Porous Materials Prepared by Powder Metallurgy

利用粉末冶金法制备了不锈钢多孔材料,研究了造孔剂含量对其孔隙率和抗压强度的影响。结果表明:随着造孔剂含量的增加,不锈钢多孔材料的平均孔隙率增大、抗压强度下降;造孔剂的质量分数控制在40%～50%之间时,可在保证强度的前提下使不锈钢多孔材料具有较高的孔隙率。

Stainless steel porous materials were prepared by powder metallurgy method, and the effect of pore-forming material contents on the porosity and compressive strength was studied. The results show that the average porosity of the stainless steel porous materials increased and their compressive strength of the materials decreased with the increase of pore-forming material content. The mass fraction of pore-forming material being 40% --50% could make the strain[ess steel porous material owning high porosity.
