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

Can Cerakote post-processing protect AM parts in high-temperature industrial environments?

Yes. Cerakote V-Series formulations are rated to 2,000 degrees F, providing thermal protection for AM parts deployed in high-temperature industrial applications. The coating also serves as a thermal barrier, reducing heat transfer into the AM substrate. For polymer AM parts, H-Series Cerakote provides protection at standard industrial operating temperatures while adding the corrosion and chemical resistance that raw PA12 and PA11 surfaces lack. Temperature requirements drive formulation selection during our engineering review.

Can Cerakote protect high-wear surfaces like slides, rails, and bearing journals?

Yes. Elite Series Cerakote combines the 4,000 cycles per mil abrasion resistance with a ~0.11 coefficient of friction, providing both wear protection and dry lubrication on sliding surfaces. At 0.5-2 mils thickness, the coating preserves the clearances on precision slides, linear rails, and bearing journals that thicker coatings would close up. The dry lubrication eliminates the need for wet lubricants that attract contamination in dusty or dirty environments.

How does polymer coating protect industrial pump and valve components?

Pump housings, valve bodies, and flow-path components that handle corrosive fluids benefit from polymer coating's combination of chemical resistance and flexibility. The coating accommodates thermal expansion, pressure cycling, and vibration without cracking or delaminating. For applications requiring both internal chemical resistance and external wear protection, we apply polymer coating internally with Cerakote externally. This combination addresses the different stress modes on each surface.

How does Cerakote protect medical instruments through sterilization cycles?

Cerakote's 3,000-hour salt spray resistance and chemical resistance withstand repeated autoclave sterilization at 250°F to 275°F, enzymatic cleaning solutions, and chemical disinfectants without degradation. The 9H pencil hardness prevents scratching during instrument tray loading and surgical use. This corrosion and wear resistance combination extends instrument life significantly compared to anodized or uncoated stainless steel surfaces.

Why does Cerakote's weight advantage matter for aerospace applications?

Every ounce matters in aerospace. Cerakote's 0.5 to 2 mil film build versus powder coat's 4 to 6 mils reduces coating weight by 50 to 85 percent across thousands of cabin interior components, brackets, and fixtures. This weight reduction translates directly to fuel savings over the operational life of the aircraft. The thinner film also preserves critical tolerances on seat mechanisms, latch hardware, and precision-fit components.
