Effects of Attrition on Microstructure of Electroformed Nickel

摘要

The nickel deposits of different microstructures were obtained by electroforming with abrasive-assisted. The effects of friction strength on the surface morphology and the microstructures of the deposits were studied. The results indicate that the deposits with homogeneous microstructures were obtained with the horizontal cathode, during the abrasive-assisted electroforming process of nickel. The surface smoothness was improved and the nickel crystal grain was refined with the increasing linear velocity. The nickel deposits could be obtained with a wide range of microstructures at different speed of the rotating cathode, which the grain size was in the range from 100nm to 600nm. The difference value of growth rate of the various crystal faces is getting smaller with the increasing velocity of the cathode.
