Electropolishing, sometimes called reverse electroplating, is an electrochemical process which polishes a metal surface by removing a microscopic amount of material from the work piece. Electroplating is the coating of an electrically conductive item with a layer of metal using electrical current. ... Electrochemistry is the study of the electronic and electrical aspects of chemical reactions. ... Metal - Wikipedia, the free encyclopedia /**/ @import /skins-1. ...


In electropolishing, the metal work piece is immersed in a temperature controlled bath of electrolyte and connected to the positive terminal (anode) of a DC power supply. The negative terminal is attached to a cathode to which the particles removed from the anode (the work piece) are attracted when electric current is applied. Often, the size, position and distance of the cathode to the work piece is controlled during the process in order to achieve the desired level of polish and to localize areas of polish. An electrolyte is a substance which dissociates free ions when dissolved (or molten), to produce an electrically conductive medium. ... Diagram of a zinc anode An anode (from the Greek άνοδος = going up) is the positive electrode in an electrolytic system or circuit. ... Direct current (DC or continuous current) is the continuous flow of electricity through a conductor such as a wire from high to low potential. ... Diagram of a copper cathode in a Daniells cell. ...


The process also passivates the surface by leaving a very thin layer of chromium-enriched material. General Name, Symbol, Number chromium, Cr, 24 Chemical series transition metals Group, Period, Block 6, 4, d Appearance silvery metallic Atomic mass 51. ...

Delstar Electropolishing Passivating and Mechanical Polishing (265 words)
Electropolishing is an electrochemical process similar to, but the reverse of, electroplating.
The electropolishing process smoothes and streamlines the microscopic surface of a metal object.
All of these oxide layers are generally referred to as "scale" and must be removed prior to Electropolishing or Passivating.
