š§Ŗ Chemical Conversion Coating: What It Is, and Why You Need It
In aviation maintenance, corrosion is the silent enemy. It eats away at metal, weakens components, and risks the airworthiness of your fleet. Thatās whereĀ chemical conversion coatingĀ steps ināas a crucial first line of defense.
At Jets MRO Miami, our FAA/EASA-certified team applies MIL-DTL-81706 and MIL-DTL-5541 compliant conversion coatings to protect high-value aerospace components from corrosion and surface degradation.
Hereās what that meansāand why it matters.
š What Is Chemical Conversion Coating?
Also known as chem film or alodine, chemical conversion coating is a surface treatment applied to aluminum and aluminum alloys. It forms a protective, corrosion-resistant layer without altering part dimensions.
Itās typically used before painting, bonding, or as a standalone corrosion barrierāespecially on components exposed to harsh environments.
š What Are MIL-DTL-81706 and MIL-DTL-5541?
- MIL-DTL-81706 sets the material and application requirements for conversion coatings used in aerospace and military applications. It governs the chemicals used.
- MIL-DTL-5541 defines the performance standards of the final coatingālike corrosion resistance and electrical conductivity.
Jets MRO Miami uses only qualified materials and processes that meet both specifications, ensuring reliable, certifiable protection for every treated component.
āļø Why It Matters for Aircraft Components
Key Benefits of Chemical Conversion Coating:
ā
Corrosion Resistance: Prevents oxidation and surface damage on exposed aluminum
ā
Adhesion Promoter: Improves paint bonding, reducing the risk of flaking or peeling
ā
Electrical Conductivity: Retains conductivity on critical bonding or grounding surfaces
ā
Non-Dimensional: Ideal for precision componentsāno impact on tolerances
ā
Compliant & Certifiable: Meets military and aerospace documentation standards (including FAA 8130 dual release)
āļø What We Treat at Jets MRO Miami
We apply conversion coatings as part of our in-house component repair process, including on:
