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%。A novel technique of flexible compression electroforming was described by the experiments of W fiber reinforced Ni,where the mechanism of the flexible compression was presented.Theoretical analysis and experimental results show that the friction and extrusion between the flexible compression wheel and the cathode may effectively remove the hydrogen bubbles which reduces the surface porosity;the effects of solution supplement by the flexible compression wheel may prevent the generation of the internal voids and raise the limiting current density which reduces the grain size significantly.When the volume fraction of tungsten wire is as 50%,the tungsten-Ni comqosite electroforming layer strength is up to 1597 MPa,which improves by 21%.
