摘要: 采用粉末冶金法对40(50Cu-Ni)-(NiFe2O4-10NiO)金属陶瓷进行MnO掺杂实验,并对不同添加量试样进行烧结致密化与电解腐蚀性能研究。结果表明:在烧结过程中Mn2+会取代部分基体尖晶石中Ni2+发生晶格畸变,提高烧结活性,当添加量为3wt;时,试样收缩率为18.5;,致密度达97.7;;24 h杂质含量最低,电解24 h后铝液中的Cu、Fe、Ni、Mn的杂质含量最低,分别为0.069wt;、0.121wt;、0.115wt;、0.028wt;。

Abstract: The modification experiments focuses on the 40(50Cu-Ni)-(NiFe2O4-10NiO) with MnO in powder metallurgy, The density and corrosion of electricity were studied by different amount of sample, results show that Mn2+ replace part of the matrix Ni2+ during sintering, lattice distortion occurs, increasing the sintering activity. The sample is 18. 5; shrinkage rate when the addition amount of 3wt;, density up to 97. 7;. The impurity content is lower after 24 h electrolysis,the content of Cu, Ni, Mn in aluminum liquid is 0. 069wt;,0. 121wt;,0. 115wt;,0. 028wt;,respectively.
