摘要
实验以碳酸氢铵(NH4HCO3)为造孔剂,通过粉末轧制技术制备了孔隙率为22.2％～52.4％的多孔镍板.研究了造孔剂含量对多孔镍板组织性能的影响.结果表明:随着造孔剂含量的增加,多孔镍板的孔隙率逐渐增大,相对透气系数也逐渐增大,而抗拉强度逐渐降低.当造孔剂含量为20％时,多孔镍板的孔隙率为40.7％,相对透气系数为10.79 m3/(h·kPa·m2),抗拉强度为135 MPa;当造孔剂含量为40％时,多孔镍板的孔隙率为52.4％,相对透气系数为41 m3/(h·kPa·m2),抗拉强度降低至51 MPa.
Abstract
Porous nickel plates with porosity of 22.2％-52.4％were prepared by powder rolling technology using ammonium bicarbonate(NH4HCO3)as pore-making agent.The effect of pore-forming agent content on microstruc-ture and properties of porous nickel plate was studied.The results show that with the increase of pore-forming agent content,the porosity of porous nickel plate increases gradually,the relative permeability increases gradually,and the tensile strength decreases gradually.When the content of pore-forming agent is 20％,the porosity of porous nickel plate is 40.7％,the relative permeability coefficient is 10.79 m3/(h·kPa·m2),and the tensile strength is 135 MPa.When the content of pore-forming agent is 40％,the porosity of porous nickel plate is 52.4％,the relative permeability coefficient is 41.0 m3/(h·kPa·m2),and the tensile strength is reduced to 51 MPa.
