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%。
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.
