This document describes a low stress automated polishing device that was developed to prepare titanium and nickel alloy samples for imaging with electron microscopy. The system uses pulsed electrochemical reactions within an alkaline electrolyte to generate a thin passivation layer on the surface of the sample, which is removed by the mechanical vibration of the system. This research documents the passivation layer development and removal for Ti-6Al-4V and nickel 718 ...
