Surface Morphology and Texture of Nickel Crystal Micro-Casting by Electroforming under Magnetic Field

Abstract

Micro-components were electroplated using composite electroforming technology under magnetic field. The surface morphology of the micro components was examined using scanning electron microscope (SEM) and X-ray spectrometer was used to detect texture. The results show that: the texture and surface morphology of the micro components are influenced by the current density and the magnetic field intensity. With the increase of current density, the size of crystal grains decrease firstly but increase later .And as the increase of the magnetic field intensity, the size of crystal grains become smaller and more uniform. Besides, the current density and the magnetic field intensity have a great impact on the texture of castings. As the increase of the current density, the texture orientation changes from (111) to (200). At the same time, along with the increase of the magnetic field intensity, the diffraction peak (200) is suppressed while the diffraction peak (111) is enhanced obviously.
