Key Takeaways: A380 Is a Practice: It guides the methods for cleaning, descaling, and passivating stainless steel, not pass/fail limits. A380 vs A967: A380 explains the process; A967 sets the passivation acceptance criteria and testing thresholds. Aerospace Fit: Both...
Key Takeaways: Performance-Based Spec: MIL-PRF-23377 defines corrosion, chemical, and solvent resistance for high-solids epoxy primers on aerospace substrates. Type + Class Precision: Correctly pairing Type (pigment) and Class (chromate vs. non-chromate) is critical...
Key Takeaways: Performance, not recipe: MIL-PRF-85285 defines how a topcoat must perform, not how it’s formulated, so compliance rides on qualification testing. QPL is non-negotiable: Only products listed on QPL-85285 are eligible for federal contract award,...
Key Takeaways: Purpose-Driven Process: Abrasive blasting cleans, strips, and textures aerospace surfaces without adding the controlled compressive residual stress that shot peening delivers. Media Matters: The right abrasive material depends on the alloy, geometry,...
Key Takeaways: Yes, With Prep: Aluminum can be powder-coated effectively when the surface is properly cleaned and pretreated to ensure adhesion and corrosion resistance. Durability Edge: Powder coating typically outperforms liquid paint in impact, chipping, and...
