Corrosion Risks and Mitigation Strategies in Spacecraft, Launch Vehicle, Aircraft, and Missile
The selection and validation of materials based on specific application requirements are fundamental to ensuring the structural integrity and mission success of spacecraft, launch vehicles, aircraft, and missiles. These materials are deemed mission-critical, as any failure can compromise the performance and reliability of multimillion-dollar aerospace and defense systems.
A key criterion in material selection is resistance to various forms of corrosion, including atmospheric corrosion, stress corrosion cracking, and galvanic corrosion. Components fabricated from these materials are often considered single-point failure items—any defect or degradation can jeopardize the entire mission.
This presentation explores the detailed mechanisms behind atmospheric corrosion, stress corrosion cracking, and galvanic corrosion, supported by examples. It also outlines effective mitigation strategies and remedies to alleviate corrosion-related risks, ensuring long-term durability and operational success.
