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


Saltwater Corrosion Is Relentless
Marine environments test every coating to failure
The challenge
Harsh environments demand coatings that hold.
The solution
ColoradoKote ceramic coating stops corrosion cold.
Why Cerakote for Maritime Corrosion
Molecular-level saltwater barrier on all marine metals
4,000+ Hours Salt Spray Resistance
ASTM B117 verified on marine-grade metals. Molecular barrier blocks salt spray, humidity, and direct immersion. Outperforms marine paint by years, not months.
All Marine Metals Protected
Single coating system bonds to stainless, aluminum, bronze, and carbon steel. Eliminates galvanic corrosion risk at dissimilar metal interfaces in marine assemblies.
UV Stable
Resists UV degradation and chalking in direct marine sunlight. Color and gloss retention maintained without the recoating schedule that marine paint demands.
Thin-Film Marine Protection
Full corrosion resistance at 0.5-2 mils. Maintains fit and function on marine hardware, fittings, and fasteners where thick coatings cause interference.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Ultrasonic cleaning uses a transducer to generate 40 kHz sound waves in a cleaning solution, creating millions of microscopic cavitation bubbles. These bubbles form and collapse rapidly, producing localized high-energy implosions that dislodge contaminants from surfaces, blind holes, internal passages, and complex geometries. The 40 kHz frequency provides an effective balance between cleaning aggressiveness and surface safety for the range of substrates we process. Cleaning solution chemistry is matched to the substrate material and contamination type.
Medical instruments and device housings have tight tolerances for proper function, sterile seal integrity, and assembly fit. Cerakote's 0.5 to 2 mil application preserves these dimensions where thicker coatings would interfere. This is particularly critical for implantable device housings, endoscopic instrument shafts, and robotic surgery components where micron-level dimensional accuracy determines performance and patient safety.
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.
ColoradoKote applies biocompatible Cerakote formulations to surgical instruments, implantable device housings, orthopedic tooling, and diagnostic equipment components. Our ISO 9001:2015 quality system provides the process documentation and traceability medical device manufacturers require for regulatory submissions. Cerakote's chemical resistance protects instruments through repeated autoclave sterilization cycles.
Chemical conversion coating is an excellent first line of defense for aluminum components in marine environments. MIL-DTL-5541 Type I delivers 168-240+ hours of salt spray resistance per ASTM B117, providing meaningful standalone protection. For components with sustained saltwater immersion or spray exposure, we strongly recommend the chem conversion plus Cerakote stack, which delivers 3,000 hours of salt spray protection in a coating system thinner than conventional marine paint.
