【摘要】:提出了一种新的柔性受压电铸技术,从理论上深入探讨了柔性受压的作用机理,并通过钨丝增强镍的电铸试验进行了验证。理论分析和试验结果表明:柔性压紧轮对复合电铸层的摩擦与挤压作用可以有效去除复合电铸层表面的吸附气泡,获得表面无缺陷的复合电铸层;柔性压紧轮能够不断补充电沉积区域的电铸液,防止复合电铸层内部出现空洞,并能提高极限电流密度,显著细化晶粒;柔性受压条件下获得的复合电铸层具有更高的强度,当钨丝体积分数为50%时,制得的钨丝-镍复合电铸层强度达到1597MPa,提升了21%。
[Abstract]:A new flexible pressure-electroforming technique is proposed. The mechanism of flexible pressure-induced electroforming is discussed theoretically and verified by electroforming experiments of tungsten wire reinforced nickel. The theoretical analysis and experimental results show that the friction and extrusion of the composite electroforming layer by the flexible compaction wheel can effectively remove the adsorption bubbles on the surface of the composite electroforming layer and obtain the composite electroforming layer with no defects on the surface. The flexible compaction wheel can continuously replenish the electroforming fluid in the electrodeposition area, prevent the internal cavity from appearing in the composite electroforming layer, increase the limit current density, and refine the grain significantly, and the composite electroforming layer obtained under the flexible compression condition has higher strength. When the volume fraction of tungsten wire is 50, the strength of tungsten wire-nickel composite electroforming layer is 1597 MPA, which increases 21%.
