中文摘要：

进行了粉末、烧结气氛和烧结温度对支撑体孔径、透过性能影响的研究。结果表明,获得了支撑体材料的制备工艺窗口,原料粉末应选粒度≥100μm,烧结温度在1150~1300℃之间调整。环拉实验结果表明,氢气烧结样品的抗拉强度87.56 MPa,氢气＋氯化铵活化烧结样品115.20 MPa,强度提高了30%。通过烧结温度对支撑体力学性能影响的研究,得到了支撑体致密度和力学性能之间的关系,可实现通过测试多孔材料的密度来预测多孔材料的强度。

英文摘要：

The effects of powder,sintering atmosphere and sintering temperature on pore radius and permeability of porous support were investigated. The formation process of the support layer using metal powder was obtained. Results show that the average particle size of initial powder is ≥100 μm and the support layer is sintered at 1150~1300 °C for 2 h. Ring tensile results show that tensile strength of H_2 atmosphere sintered sample is 87.56 MPa while that of an activation atmosphere of H_2 with 0.2 wt% NH_4Cl addition sintered sample is 115.20 MPa,which is enhanced by 30%. The effects of sintering temperature on mechanical properties of porous support were also investigated. The relationship between density of porous support and mechanical properties was obtained. The relationship could be used to forecast the strength of porous materials by testing density of porous materials.
