2.1 Methods of Passivation: Nitric Acid vs. Citric Acid
The passivation process outlined in AMS 2700 involves two primary methods: nitric acid and citric acid treatments. Nitric acid passivation is a traditional and widely used method‚ effective for removing free iron and other contaminants from steel surfaces. It ensures a robust oxide layer‚ enhancing corrosion resistance. Citric acid passivation‚ on the other hand‚ is a more environmentally friendly alternative‚ producing fewer hazardous byproducts while achieving similar results. Both methods are detailed in the AMS 2700 specification‚ with specific parameters for temperature‚ concentration‚ and immersion time. The choice between the two depends on environmental considerations‚ cost‚ and the specific requirements of the application. Each method ensures the steel surface is properly passivated‚ meeting the standard’s rigorous criteria for corrosion resistance and durability.
2.2 Steps Involved in the Passivation Process
The passivation process as per AMS 2700 involves several critical steps to ensure effective removal of contaminants and formation of a protective oxide layer. First‚ the steel parts undergo thorough cleaning to eliminate dirt‚ oil‚ or grease. Next‚ the parts are immersed in either nitric or citric acid solution‚ with carefully controlled temperature and concentration levels. Following the acid treatment‚ a rigorous rinsing process is performed to remove residual acid. Drying is then conducted to prevent water spots. Finally‚ the parts undergo inspection and testing‚ including visual examination and corrosion resistance tests‚ to ensure compliance with the specification. These steps are essential for achieving optimal passivation results.

Testing and Verification
AMS 2700 requires rigorous testing‚ including salt spray and visual inspections‚ to confirm passivation effectiveness and ensure compliance with corrosion resistance standards.
4.1 Salt Spray Testing for Corrosion Resistance
Salt spray testing is a critical method for verifying corrosion resistance in AMS 2700. This method‚ detailed in ASTM B117‚ involves exposing passivated steel parts to a controlled saltwater mist environment. The test measures the material’s ability to resist corrosion over a specified period. Parts are evaluated for signs of red rust or staining‚ which indicate free iron contamination. The test duration varies depending on the application‚ but it is essential for ensuring the passivation process has effectively removed contaminants. Salt spray testing is a widely accepted standard in aerospace and defense industries‚ providing assurance of long-term corrosion resistance. It complements visual inspections and is a key step in AMS 2700 compliance.
4.2 Visual Inspection and Testing Procedures
Visual inspection is a fundamental step in verifying the quality of passivated steel parts under AMS 2700. Technicians examine surfaces for defects‚ streaks‚ or discoloration that may indicate incomplete passivation. Testing procedures include checks for uniformity and absence of contaminants. ASTM A967 provides guidelines for these inspections‚ ensuring parts meet specified standards. Visual assessments are often combined with salt spray testing to confirm corrosion resistance. Proper documentation of findings is essential for compliance. This dual approach ensures reliability and durability of components‚ particularly in critical industries like aerospace and defense.
