摘要
采用添加造孔剂的方法制备多孔铝试样。研究烧结温度和稀土氟化镧含量对多孔铝材料的性能影响。结果表明,烧结温度为600℃时多孔铝材料的烧结性能最佳;稀土氟化镧的适量加入可以提高多孔铝的力学性能;稀土氟化镧添加量为0.5%时,多孔铝材料的抗压强度和弹性模量最佳,分别为52.4 MPa和1.56 GPa。
Porous aluminum samples were prepared by adding pore forming agent.The effects of sintering temperature and lanthanum fluoride content on the properties of porous aluminum were studied.The results show that the sintering performance of porous aluminum material is the best when the sintering temperature is 600℃,the mechanical properties of porous aluminum can be improved by adding lanthanum fluoride properly,and the compressive strength and elastic modulus of porous aluminum material are the best when the adding amount of lanthanum fluoride is 0.5%,which are 52.4 MPa and 1.56 GPa respectively.
