Brush plating is a selective electrodeposition process in which a stylus or tampon saturated with electrolyte solution deposits metallic coatings — commonly nickel, cobalt, copper or gold alloys — onto localised areas of aerospace components without full-bath immersion, making it particularly suited to in-situ repair of wear, corrosion or dimensional loss on flight-critical parts in accordance with MIL-STD and OEM specifications.
