摘要
在柔性支撑下使硬质粒子对旋转阴极电铸层表面进行摩擦和碰撞,以提高电铸层的表面品质和机械性能。对比了传统电铸层和微珠柔性受压辅助磨电铸层的外观、微观组织结构和显微硬度。结果表明,微珠柔性受压辅助磨电铸所得Ni电铸层表面平整光亮,表面粗糙度Ra为0.057μm,显微硬度为398.7 HV,平均晶粒尺寸为23.7 nm。与传统电铸层相比,微珠柔性受压辅助磨电铸表面粗糙度更低,显微硬度更高,微观形貌更细致。
Hard particles were used during electroforming process to improve the surface quality and mechanical properties of nickel coating for their friction and impact onto the surface of coating at the presence of flexible compression.The appearance,microstructure,and microhardness of the nickel coatings obtained by traditional electroforming and electroforming with the assistance of friction of micro-beads under flexible compression were compared.The results showed that the Ni coating obtained by friction-assisted electroforming under flexible compression was smooth and bright with a surface roughness(Ra)of 0.057μm,a microhardness of 398.7 HV,and an average grain size of 23.7 nm.It has lower surface roughness,higher microhardness,and finer microstructure as compared with the Ni coating obtained by traditional electroforming.
