Aluminum Vapor Deposition
Ion Vapor Deposition (IVD) is a process for applying pure aluminum coatings to parts for corrosion protection. To prevent oxygen and water vapor contamination, the aluminum coating is applied to the parts in a vacuum. Ipsen's vacuum furnace for IVD is called the Ivadizer®.
The Ipsen Ivadizing system provides an alternative to cadmium plating for the Aerospace and Automotive industries. Cadmium platings were the corrosion resistance finish of choice for many years; however, cadmium is a toxic carcinogen. Cadmium electroplating is typically applied in an alkaline bath containing a sodium cyanide solution. In addition to the cadmium exposure, environmental, health and safety concerns arise with use of a cyanide bath. Unlike cadmium, aluminum is environmentally clean, nontoxic and safe for operating personnel to handle and use.
The Ivadizer® plating equipment uses Ion Vapor Deposition to apply a dense, high-performance coating of aluminum with superior adhesion and thickness uniformity. Since the Ivadizer® furnace creates a plasma-assisted coating, it provides excellent throwing power, extending the deposit readily into part cavities. Even temperature-sensitive parts can be coated safely and effectively using the Ivadizing process. Our basic models, which include a rack coater for large components and a barrel coater for small, high-volume parts, provide:
- Environmentally friendly operation
- Low temperature processing
- Fully equipped evaporator system
- Optimized evaporation speed
