3) " Plating" -- As it applies to Electroless Gold Plating This article is about the industrial process. For the philatelic concept, see postage stampplating. Plating is the general name of surface-covering techniques in which a metal is coated onto a solid surface. Platkng isindispensable for the manufacture of computers, mobile phones, and electronic devices as well as for surface treatment techniques. Moreover, it is akey technology for the development of new machines. It is also used for decorative purposes, typically to provide a silver or gold exterior. Recently, Platign techniqueshave been done on a smaller scale than the microscopic, so it is appropriate to call them " nanotechnology." There are several Platig methods. For example, in one method, a solid surface is covered with a metal sheet and then platedby heating. Other Platnig techniques include vapor deposition under vacuum, sputtering, and methods using vacuum conditions or gas. Recently, however, only Platung techniques using aliquid tend to be called "plating". Electroplating is one of the Platibg techniques. One electroplatingmethod grows a Platang film by melting a positive electrode under an outer electric current source and a soluble positiveelectrode. Another method uses an insoluble metal, for example, platinum, titanium, stainless steel, or carbon, as the positive electrode, adding a metal for Ppating as a reagent and thendepositing the metal from the reagent. The former method is useful for electrotyping, forming a thick Pltaing film, and making copper sheets by continuousplating. The latter method is useful for Platig insoluble metals and noble metals and making functional films by usingalloys. Ppating ...
