“…133,143,145,146 Normally, the preparation of the thin TEM specimen is composed of three steps, (a) obtaining a sample piece less than 2 mm thick, (b) mechanically thinning the sample down to about 0.2 mm and (c) further decreasing the sample thickness down to nanometre range so that sufficient electron beam penetration can occur. 147 The key factors of electropolishing, including voltage, current density, temperature, electropolishing duration and convective flow rate need to be carefully optimised in order for one to obtain an ideal TEM sample for reproducible observation. Necip 148 prepared high quality pure aluminium TEM samples through a double-jet electropolishing technique.…”

Electropolishing is the electrochemical process to remove the metallic material from the workpiece, in order to obtain a smoother metal surface. It has found vast engineering applications in many fields, such as food, medical, pharmaceutical and semiconductor industries. This review is aimed to provide the readership with insightful understanding of the electropolishing process, from the fundamental aspects as well as from the application aspects. The general aspects of electropolishing, including its definition, the classic setup, the fundamentals behind it and methods used to evaluate the electropolishing finishes are reviewed here. Various electropolishing theories, be them quantitative or qualitative are briefly discussed. Based on those theories, important parameters evolved in the electropolishing process are enumerated. Many microscopic technologies are used to evaluate the electropolishing surface finishes. This includes optical microscope, electron microscope and atomic force microscope. Some key features of electropolishing are briefly outlined in the end.
