CHEMICAL VAPOR ALUMINIZING EQUIPMENT The Bernex™ CVA ALUVAP systems are a further development of the Bernex CVD platform, dedicated to the diffusion of aluminum. CVA is highly suited for superalloy components like hot-section turbine blades of aircraft engines and land-based gas turbines, which are subject to hot corrosion. The CVA vacuum process uses gaseous precursors and provides Advantages: very accurate control of diff usion depth and thickness over all inner Active gas flow that reaches internal cooling channels and outer surfaces of the parts, irrespective of their geometrical Controlled high and low activity processes complexity. Dual reactor design for high capacity The design of the Bernex™ CVA system allows for the control In contrast to the conventional pack, out of pack, above the pack of high and low diffusion activity as well as co-diffusion of and slurry processes, CVA does not clog internal channels and elements such as silicon, chromium, zirconium, hafnium or cobalt, l
