4D Quench® / UniCase Master – Single‑Piece Flow Vacuum Quenching System
A vacuum system for single‑piece nitrogen quenching with distortion control, offering an alternative to press quenching with high repeatability and

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.
IVD aluminum coating is widely used in:
IVD systems are used and certified by major aerospace manufacturers, with installations referenced in the uploaded catalog including leading aviation companies in Europe. Compatible with aerospace coating standards such as MIL-DTL-83488.
