Industrial, Medical and Art Restoration Applications of Surface Texturing (TOP3-71)
Abstract:Surface texturing can improve orthopaedic implants and increase cellular attachment, make transmitted light more diffuse, reduce surface glare, change friction and wetability of a surface, improve heat transfer, and produce many other beneficial effects. Some of the same technology can be used to remove thin organic coatings, such as adhesives, varnish, and soot, from surfaces. The process involves no physical contact with the surface, which makes it attractive for cleaning delicate art objects. Surface texturing can be produced by a variety of techniques; the simplest technique for metal surfaces is arc texturing.

Surface texturing can be produced by a variety of techniques; the simplest technique for metal surfaces is arc texturing. This involves producing a low-voltage, moderate-current arc between the surface and an electrode composed of either carbon or silicon carbide. The arc produces pits in the surface and deposits some of the carbon from the electrode, which also enhances the surface roughness. Finer textures can be produced either by bombarding the surface with a high-energy beam of inert gas ions through a mask, with simultaneous arrival of masking atoms from another source, or by allowing the surface to develop a natural texture. Very fine surface texturing of organic surfaces or removal of organic layers can be accomplished with a low-energy beam of oxygen atoms. The oxygen atoms chemically react with the organic surface (layer) and convert it
