Abstract

The electropolishing of a B-doped diamond (BDD) film deposited by CVD was studied in HOAc-H2SO4 media. The electropolished surface was characterized by SEM, XPS, and electrochem. measurements. In 1 M H2SO4 no polishing of the surface occurred even after prolonged time; on the contrary, in electrolyte contg. 3 M HOAc in 1 M H2SO4 the morphol. changed rapidly. The surface became smoother and the roughness decreased as the typical results of a polishing process. All the nondiamond impurities were also removed by the electropolishing treatment in HOAc media.

Electropolishing

Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish. Electropolishing is often compared to, but distinctly different from, electrochemical machining. It is used to polish, passivate, and deburr metal parts. It is often described as the reverse of electroplating.

Surface tension

Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged. At liquid–air interfaces, surface tension results from the greater attraction of liquid molecules to each other (due to cohesion) than to the molecules in the air (due to adhesion). There are two primary mechanisms in play.

Surface

A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth".
