Abstract
This research aims to study the electropolishing conducted under vacuum status. The electropolishing can be used to finishing high purity components of SUS 316L to make them shine and without leaving residual stress, micro-cracks, etc. In the research, the electropolishing process parameters are selected, such as current density, degree of vacuum and polishing time to conduct the electropolishing experiment. The experimental results show that the bubbles attached to the surface of the work-piece in the vacuum state are reduced, thereby improving the surface roughness and surface pitting. The vacuum status in the process can improve the electropolishing process.
