Overview
Vacuum aluminum coating
Ion Vapor Deposition (IVD) is an advanced vacuum metallizing process used to apply pure aluminum coatings to metallic components, primarily in the aerospace and defense sectors. uses an electrically heated aluminum source inside a vacuum chamber. Aluminum is vaporized, ionized and transported toward the part, forming a dense, uniform, and highly adherent metallic layer.
IVD coatings offer exceptional corrosion resistance comparable to electroplated cadmium without environmental hazards. The process also provides excellent surface coverage on complex shapes, threaded features, and internal geometries. Typical applications include aerospace fasteners, landing gear components, engine brackets, structural parts, hydraulic components, and EMI/RFI shielding parts.
SECO/WARWICK IVD systems integrate a vacuum furnace chamber, aluminum evaporation sources, power controls, fixture systems, and optional pre-cleaning modules such as Fluor Ion Cleaning (FIC) for surface activation.
Applications
