摘　　要：采用摩擦辅助电铸技术,研究当阴极电流密度为4.0 A/dm^(2)时,钴-镍阳极面积比的变化对镍钴合金电铸层显微硬度、组成和结构的影响。结果表明:当钴-镍阳极面积比由15%增大到25%时,镍钴合金中钴含量显著增加,从43.5%增加到63.5%,镍钴合金铸层显微硬度从603 HV提高到635 HV;当钴-镍阳极面积比继续增大到55%时,钴含量几乎不变,但显微硬度仍从635 HV提高到671 HV,电铸层晶粒呈逐渐细化的趋势。各镍钴合金电铸层均具有面心立方结构和密排六方结构。The effect of the variation of the ratio of Co anode area to Ni anode area on the structure of Ni-Co electroformed deposits was investigated under the friction-assisted electroforming technique at a cathode current density of 4.0 A/dm^(2).The results show that when the ratio increased from 15%to 25%,the Co content in the Ni-Co alloys increased from 43.5%to 63.5%,and the microhardness increased from 603 HV to 635 HV;when the ratio continued to increase to 55%,the Co content did not change much,and the microhardness increased from 635 HV to 671 HV,and the grains of the electroformed deposits show a gradual refinement.The electroformed deposits of Ni-Co alloys have the face-centered structure and the tightly packed hexagonal structure.
