Corrosion Prevention for Aerospace Metals

Corrosion prevention is an important component of aerospace engineering and maintenance when it comes to metal parts. Corrosion can weaken and damage metals in aircraft, potentially leading to catastrophic failures if not properly addressed. This blog post will provide an overview of the basics of corrosion prevention for aerospace metals.

What Is Corrosion?

Corrosion is a natural process that occurs when metal surfaces come into contact with oxygen and form oxidation. This oxidation causes the metal to corrode, weakening it over time. While most metals are susceptible to corrosion, some materials are more resistant than others depending on their composition.

How Can You Prevent Corrosion?

The best way to prevent corrosion is by taking proactive steps during the design process. Aerospace engineers should pay close attention to material selection when designing aircraft components and structures, as different materials have varying levels of resistance to corrosion. In many cases, selecting a material with higher resistance can help reduce the risk of corrosion-induced failure in an aircraft component or structure. It’s also important to consider the environment in which the part or structure will be used—for example, exposure to saltwater or high levels of humidity can accelerate corrosion rates—and select a material accordingly.

In addition to selecting the right materials during the design process, there are several other steps you can take to prevent corrosion in aerospace metals. For example, using protective coatings on exposed surfaces can help create a protective barrier between the metal surface and oxygen-rich environments that could lead to oxidation and corrosion. Additionally, proper maintenance practices such as regular cleaning and inspection can help identify potential problems before they become serious issues that require expensive repairs or replacements down the line.


Corrosion prevention is critical for keeping aerospace metals in good condition throughout their life cycle. By selecting appropriate materials during the design phase and following proper maintenance protocols such as applying protective coatings and inspecting regularly, you can ensure that your parts remain safe from corrosive forces over time. With these strategies in place, you’ll have peace of mind knowing that your aircraft components are well-protected against potential damage due to corrosion.
