IP stands for Ionic Plating, a method of applying corrosion-resistant metal coatings. The article is placed in argon gas, together with some coating metal, which vaporizes on heating and becomes ionized (acquires charged atoms) as it diffuses through the gas to form the coating. It has important applications in the aerospace industryand also used in the watch industry. Other forms are PVD, or Physical Vapor Deposition, a general term used to describe any of a variety of methods to deposit thin film by the condensation of a vaporized form of the material onto various surfaces. The coating method involves purely physical processes such as high temperature vacuum evaporation or plasma sputter bombardment rather than a involving a chemical reaction at the surface to be coated as in CVD, Chemical Vapor DEposition. Hope this helps. Last edited on Wed Jan 7th, 2009 10:56 pm by |
