Electrolytic polishing and etching
ELOPREP 102 – electrolytic metallography preparation
Electrolytic preparation is one of the most efficient methods of Metallography – Preparation because the processing is carried out unmanned once the process has started. In addition to the advantage of rationalization, material is removed with absolutely no stress. Unlike with conventional metallographic grinding and polishing, no mechanical deformation or even heat can be introduced - surface hardening is impossible. The principle is based on the electrochemical removal process with a power source. Metal particles are anodically removed in an electrolyte suitable for the respective metal and with an adjusted current strength. The material sample forms the anode within the electrochemical cell. During the process, particles from the sample surface are continuously removed, thus reducing the surface roughness. The principle works because the peaks are removed faster than the valleys - the surface is leveled.
