Problem
Industries such as aerospace, defense, and energy require components that operate reliably at temperatures above 750 °C while resisting oxidation, creep, and hot‑corrosion. Conventional alloys and surface treatments often lack the necessary combination of high specific strength, fatigue durability, and manufacturability for advanced manufacturing processes.
Solution
Aegion supplies engineered titanium and nickel superalloys, high‑purity powders, and specialized surface‑treatment coatings designed for extreme thermo‑mechanical environments. Its alloy portfolio includes γ‑TiAl‑based titanium alloys (e.g., Aegion Gamma™) and γ/γ′‑strengthened nickel alloys (e.g., Aegion N™ and Ni‑X) that deliver high specific strength, creep resistance, and oxidation stability above 750 °C. The company produces atomization‑controlled powders optimized for laser‑based additive manufacturing (LPBF, EBM, DED) with tight particle‑size distribution, sphericity, and low oxygen content, enabling defect‑minimized builds and consistent fatigue performance. Surface‑engineering services employ CVD, PVD, and pack‑diffusion aluminide processes, as well as shot peening, laser shock peening, laser remelting, and ion implantation, to create protective Al₂O₃ or TiO₂ scales and compressive residual stresses that further improve oxidation, carburization, and hot‑corrosion resistance. These integrated material and treatment solutions support the production of turbine blades, combustor liners, heat exchangers, and other high‑stress components for next‑generation propulsion and power systems.
Target Audience
Primary customers are OEMs and component manufacturers in aerospace, defense, and energy sectors that produce turbine, combustor, heat‑exchanger, and high‑performance propulsion parts, as well as firms adopting additive manufacturing for critical hardware.
