Diffusion Coating Systems
With custom diffusion coating equipment Electron offers high-end systems for additional oxidation and corrosion protection of critical components used in the aviation & aerospace and gas turbine industry. Thanks to the large process chamber dimensions, our systems offer the highest capacity within the industry.
CVD, VPA and Pack
The application of diffusion coatings can be effected in many different ways such as Spray coatings, Powder Pack Cementation, Vapor Phase Aluminised (VPA) coatings and true Chemical Vapor Deposition (CVD) type aluminised coatings. For the deposition of chromium diffusion coatings, an additional type of pack cementation or VPA process chemistry can be used.
Extended service life for critical components
Whatever application method is used, the ultimate goal is to modify the surface of the parent alloy by enriching its aluminium content and thereby promoting the formation of a protective oxide layer. It also provides the coating with an aluminium reservoir for continuous oxide replenishment throughout the operational life of the treated component. According to the exact specifications of the coating or as prescribed by an OEM, the thickness of the coating can vary within a range between 25 - 75 µms.
CVD coating furnaces
We also offer CVD furnace systems for the deposition of aluminide coatings. These systems are designed and constructed on the basis of our many years of practical experience in processing this highly specialised and demanding process discipline.
Pack Cementation, VPA (Vapour Phase Aluminizing) and CVD diffusion coatings for protection against high temperature oxidation and corrosion conditions within gas turbine engines.
