Precision Plating of Close-Tolerance Small Diameter Holes with AeroNikl® (Nickel Sulfamate) Coatings 870752

ABSTRACT

Recent advances in Selective “Brush Plating” technology combined with selectively plated Nickel Sulfamate coatings (Known in the industry as AeroNikl), permit the precise plating of close-tolerance small diameter holes, on a repetitive basis. The ability to “plate-to-size” small diameter holes should be of great interest to anyone involved with the manufacture or overhaul of aircraft quality parts or assemblies. Many close-tolerance parts are being “scrapped” during manufacture for discrepancies of 0.001 inch on the diameter, or less. The latest fixturing and plating techniques utilized by SIFCO Selective Plating technicians can correct such discrepancies in minutes, with high quality nickel sulfamate coatings. The time consuming and costly method of masking, tank plating, and remachining is avoided in most applications.
