Corrosion Resistance for Defense

Coating adhesion requires a chemically clean substrate free of oils, machining fluids, fingerprints, and particulate contamination. Even microscopic contamination creates weak spots where the coating fails to bond, leading to adhesion failure in service. Ultrasonic cavitation reaches contaminants in blind holes, threads, internal passages, and surface porosity that manual cleaning and spray methods miss. This is why ultrasonic cleaning is integrated into our pre-coating preparation for critical applications.

Passivation per ASTM A967 / AMS 2700 removes free iron and surface contaminants from stainless steel through a controlled acid bath, bringing chromium to the surface to form a robust passive oxide layer. This restored passive layer is what gives stainless steel its corrosion resistance. The process adds no dimensional change, making it suitable for precision components. For maximum protection, passivation followed by Cerakote delivers 3,000 hours of salt spray resistance (ASTM B117).

Standard passivation turnaround is 14 days, with 7-day and 3-day expedited options to match seasonal agricultural equipment production schedules. We handle batch orders of all sizes and maintain consistent processing quality, backed by over 20,000 parts with zero quality issues. For operations running both stainless and aluminum components, we can process both materials under one roof to simplify your supply chain.

Yes. Engine blocks, intake manifolds, valve covers, and exhaust components all receive blast preparation tailored to the substrate material and operating temperature. Exhaust components destined for V-Series Cerakote (rated to 2,000 degrees F) are blasted to ensure adhesion under extreme thermal cycling. Aluminum engine components receive media selected to avoid iron contamination. All automotive blast work follows the same documented process controls as our aerospace operations.

Aircraft cabin components face a combination of humidity cycling, galley chemical exposure, lavatory cleaning agents, and passenger contact that accelerates corrosion on unprotected or poorly coated surfaces. Cerakote's 3,000-hour salt spray performance and chemical resistance protect seat frames, galley hardware, and interior fixtures through thousands of flight cycles. The thin 0.5 to 2 mil film build adds negligible weight across the hundreds of components in a cabin interior.
