【摘要】 通过直流复合电沉积和脉冲复合电沉积分别制备出纳米复合电铸层,探讨了复合电铸层中纳米颗粒复合量对基质金属晶面取向的影响。结果表明,纳米颗粒的存在改变了基质金属镍的晶体择优取向。当复合电铸层中纳米颗粒的复合量较少时,基质金属Ni沿(200)晶面结晶取向较强,而当复合电铸层中ZrO2复合量较大时,基质金属Ni的择优取向不明显。更多还原

【Abstract】 The nano-composite electroforming deposits were prepared by direct current and pulse current.The effect of content of nanoparticle on the preferential orientation of the metallic matrix of nano-composite electroforming deposits was investigated.Results indicate that the crystal orientation preferential of the metallic matrix Ni is changed owing to the existence of nanoparticle in the composite electroforming deposits.The crystal preferential orientation is(200) crystal face when the content of nanoparticles in the composite deposits is lower.The crystal preferential orientation becomes unclear with the increase of the content of nanoparticle.更多还原
