Bernex™ CVA diffusion coatings for jet engine turbine sections
Ionbond offers a special class of coatings to provide protection against high-temperature oxidation and hot corrosion in the hot section of jet engine turbines. These coatings are based on chemical vapor deposition (CVD) diffusion aluminizing, also known as CVA, and are offered by Ionbond under the brand name Ionbond™CVD 66.
Unlike pack aluminizing, CVA coatings can be easily deposited onto internal surfaces, such as the cooling channels of blades, vanes or other turbine components. In addition, the CVA process opens up virtually unlimited possibilities to dope the coatings with elements such as Hf, Cr and Si to further increase their performance.
