Most applications of metals require that the surface be modified, pretreated, or finished for corrosion protection, appearance, or adhesive bond strength and durability. The use of adhesively bonded structures in automotive and aircraft design is increasing rapidly. Surfaceprocessing techniques such as anodizing, electroplating, etching, conversion coating, and painting frequently involve the use of toxic materials such as hexavalent chromium, cyanides, and lead compounds and thus produce pollutants. Disposing of the effluents is a serious environmental problem which increases production costs unnecessarily. Brighton Technologies Group, Inc. proposes a program of research aimed at developing a commercially viable plasma etching and plasma polymerization process as a high-performance, cost-effective, non-polluting surface pretreatment process suitable for steel, galvanized steel, galvalume-coated steel, and aluminum. The project objectives are to extend the previously developed plasma cleaning and film deposition techniques to produce a commercial process by the establishment of clear relationships between process parameters, film structure, deposition rate, and performance. This will be accomplished through a series of designed experiments whereby process parameters are modified in a controlled manner according to the results obtained from extensive mechanical testing and surface and interface analysis of the resultant films and composite structures.
