- Thin layers of secondary material are plated on substrates either by plating or spraying processes. Plating operations produce large amounts of hazardous liquid wastes. Spraying, while one of the less waste intensive methods, produces ``over spray`` which is waste that is a result of the uncontrolled nature of the spray stream. In many cases the over spray produces a hazardous waste. Spray coating is a mature process with many uses. Material can be deposited utilizing spraying technology in three basic ways: ``Flame spraying;`` direct spraying of molten metals; and/or plasma spraying. This project is directed at controlling the plasma spraying process and thereby minimizing the waste generated in that process. Examples of spraying applications that may benefit substantially from this technology are: (1) preparing printed circuit boards; and (2) tinning circuit boards with lead in preparation for soldering components. There are many applications of spraying technology that can benefit from a controlled spraying scheme. They include: (1) titanium coating on bio-implants; (2) wear-tolerant ceramic thermal barriers using partially stabilized zirconia (PSZ); (3) alumina and alumina-titania wear resistant-coatings: and (4) ceramic superconductor manufacture using Hollow Spherical Powders.
