摘　　要：采用两步烧结法制备(85Cu-15Ni)/TiN/NiFe_(2)O_(4)复合惰性阳极材料,重点研究了金属添加量(质量分数,下同)对复合惰性阳极材料致密度、抗弯强度、抗热震性、耐腐蚀性和导电性的影响.研究结果表明:随着85Cu-15Ni金属添加量的增加,复合惰性阳极材料的致密度、抗弯强度和抗热震性能均呈现先升高后降低的趋势;当金属添加量为10%时,复合惰性阳极材料的综合性能最佳,气孔率取得极小值2.86%,体积密度取得极大值4.96 g/cm^(3),抗弯强度达到最大值90.76 MPa,强度剩余率达到最大值88.61%.添加一定量的金属可以改善复合惰性阳极试样的致密度和晶界结合强度,提高材料的强度、抗热震性、耐腐蚀性和导电性.(85Cu-15Ni)/TiN/NiFe_(2)O_(4) composite inert anode materials were prepared by two-step sintering method.The effects of metal additions(mass fraction)on the density,bending strength,thermal shock resistance,corrosion resistance and electrical conductivity of the composite inert anode materials were studied.The results showed that the properties(namely density,bending strength and thermal shock resistance)of the composite inert anode material firstly increased and then decreased with the increase of 85Cu-15Ni metal addition.When the metal addition was 10%,the composite inert anode material possessed the best comprehensive with a minimum porosity of 2.86%and a maximum bulk density of 4.96 g/cm^(3).The maximum bending strength was 90.76 MPa,and the residual strength rate was 88.61%.In a certain range,adding metal phase can improve the density and grain boundary bonding strength of composite.As a result,the strength,thermal shock resistance,corrosion resistance and electrical conductivity of the materials were improved effectively.
