Bernex™ ALUVAP CVA coating systems are designed to produce diffusion coatings for protection against hot corrosion and high temperature oxidation. CVA technology is highly effective at producing so-called bond coats on the parts of the hot section of gas turbines and jet engines. It is an environmentally friendly alternative to conventional bond coating methods. CVA is also one of the very few ways to deposit a coating onto the inner surfaces of airfoils.
With CVA, aluminum is diffused into the substrate to form intermetallic compounds. The coatings can also be doped with performance enhancing elements such as Cr, Si, Hf, Zr, etc.
Bernex™ ALUVAP CVA coating systems have advanced features for safe, reliable operation in the industrial environment. Because of the long-standing expertise of Bernex engineers, the deposition process can be tuned exactly to customer specification.
