Corrosion Protection

Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.

The cost

What Happens When Corrosion Goes Unchecked

Unprotected metal components face relentless environmental attack. Moisture, salt spray, de-icing chemicals, hydraulic fluids, and temperature cycling break down surfaces over time. The damage is cumulative, and by the time it is visible, the part has already compromised system integrity.

The real cost of corrosion

  • Part replacement: Failed components require emergency procurement, disrupting production schedules and triggering expedite fees that exceed the original part cost
  • Downtime: Equipment pulled from service for inspection, repair, or replacement costs thousands per hour in aerospace and defense applications
  • Safety risk: Corroded structural components compromise system integrity and can trigger mandatory grounding events or field recalls
  • Audit failures: Non-conforming parts generate quality escapes, customer notifications, and costly corrective action investigations

These costs compound across production runs. A single unprotected batch can cascade into weeks of disruption, eroding customer confidence and threatening long-term contracts.

The answer

How Cerakote® Ceramic Coating Stops Corrosion at the Source

Cerakote® creates a molecular bond with the substrate, forming a barrier that resists corrosion at the chemical level. Unlike paint or plating that sits on the surface, Cerakote integrates with the metal.

Why Cerakote Outperforms Alternative Coatings

Anodizing provides 336-1,000 hours of salt spray resistance and works only on aluminum. Powder coating adds 4-6 mils of thickness, causing dimensional interference. Chrome plating faces increasing regulatory restriction. Cerakote delivers 3,000 hours across all metals, polymers, and composites at 0.5-2 mils, with zero hazardous waste.

Independent Competitor Comparison

In third-party ASTM B117 salt spray testing, Cerakote® achieved 3,000 hours of corrosion resistance. Competitor Xylan coating was pulled at 1,871 hours due to excessive corrosion.

Frequently Asked Questions

Find answers about our coating processes and technical capabilities

How does Cerakote protect surgical instruments?

Cerakote provides 9H pencil hardness and 4,000 cycles per mil abrasion resistance, protecting instrument surfaces through thousands of sterilization cycles and repeated clinical use. The coating's chemical resistance withstands autoclave temperatures and enzymatic cleaning solutions without degradation. At 0.5 to 2 mils thickness, Cerakote preserves the precise tolerances surgical instruments require for proper function.

How does ultrasonic cleaning prepare maritime components exposed to salt?

Marine hardware develops salt crystal deposits, biological growth residue, and corrosion products in every crevice and internal feature. Ultrasonic cavitation dissolves and removes these contaminants from complex geometries that manual cleaning cannot reach. For maritime components being recoated, thorough ultrasonic cleaning removes all chloride contamination that would otherwise initiate corrosion under the new coating. This cleaning step is essential for achieving full coating life on marine hardware.

Does ColoradoKote offer NDA protection for proprietary parts?

Yes. We routinely execute non-disclosure agreements for customers with proprietary designs, controlled technical data, or confidential specifications. Our ITAR registration demonstrates our facility's capability to handle controlled information, and we extend the same confidentiality discipline to all customer relationships. Contact us to initiate an NDA before shipping proprietary components or specifications.

How does polymer coating protect aerospace components that flex or vibrate?

Aerospace structures, particularly skin panels, flexible joints, and vibration-isolated components, need coatings that move with the substrate without cracking. Polymer coatings maintain adhesion and integrity through repeated flex and vibration cycles that would crack rigid coatings. For aerospace applications, we apply polymer coatings under AS9100 controls with the same documentation rigor as Cerakote. Where both flexibility and surface hardness are needed, we recommend a combined polymer-Cerakote system.

What defense applications does ColoradoKote support?

ColoradoKote is ITAR registered and coats weapons system components, electronics housings, vehicle-mounted hardware, and field-deployed equipment for defense programs. Our facility in Johnstown, CO maintains the security protocols and documentation controls required for controlled technical data. We offer low-visibility finishes in earth tones, flat blacks, and custom tactical colors matched to program specifications.
