Coatings
Chromalloy was the first company to develop commercially viable aluminide coatings, and continues to provide these coatings and their derivatives on parts for commercial aviation operators around the globe. We are one of the world’s largest providers of both EBPVD coatings and Low Pressure Plasma Spray Overlay coatings. Repaired parts from Chromalloy can be expertly coated to protect the components and increase their efficiency and reliability at higher operating temperatures and under severe environmental conditions. Advanced coatings pave the way for increased firing temperatures and more efficient component and system designs.
