Corrosion Protection for Maritime
Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.
The Corrosion Problem in Maritime
Where saltwater tests every surface, every day
The challenge
Harsh environments demand coatings that hold.
The solution
ColoradoKote ceramic coating stops corrosion cold.
Why Cerakote for Maritime Corrosion Protection
Built to resist continuous saltwater exposure
Saltwater corrosion barrier
4,000+ hours salt spray resistance (ASTM B117), verified by third-party testing. Marine hardware stays protected through continuous saltwater exposure, immersion cycling, and humid coastal storage. This performance far exceeds conventional marine coatings that fail within months of saltwater service.
Dimensional precision on marine fittings
0.5-2 mil coating thickness preserves tolerances on threaded fittings, fastener heads, and mating surfaces. Parts function as designed after coating without modification. Thicker coatings compromise thread engagement and hardware function on precision marine components.
ISO 9001 quality documentation
Every marine coating job is documented under ISO 9001:2015 quality controls. Certificate of Conformance includes coating thickness, adhesion results, and material batch records. Consistent documentation supports marine equipment manufacturer quality and warranty requirements.
Multi-substrate galvanic isolation
Cerakote bonds to stainless steel, aluminum, and bronze, the three most common marine hardware substrates. Coating dissimilar metal surfaces isolates them from galvanic contact, preventing the accelerated corrosion that occurs at connection points in saltwater environments.

How We Deliver Corrosion Protection for Maritime
Substrate-specific preparation for saltwater corrosion resistance
Marine Surface Preparation
Ultrasonic cleaning removes salt deposits, marine oils, and surface contaminants. Degreasing and tailored media blasting create the surface profile required for maximum corrosion barrier adhesion on stainless steel, aluminum, and bronze substrates. Masking protects threads, mating surfaces, and functional areas.
Cerakote Corrosion Barrier Application
Thin-film ceramic-polymer hybrid is applied via calibrated HVLP spray at 0.5-2 mil thickness. The coating bonds to all common marine substrates, providing molecular-level adhesion that resists saltwater delamination. In-process DFT measurements confirm thickness compliance on every part.
Quality Inspection and Documentation
Multi-point final inspection verifies coating thickness, adhesion, color consistency, and visual appearance on every lot. Certificate of Conformance documents all measurements and material batch records. ISO 9001 quality system ensures consistent results across production volumes.
Proven Corrosion Protection for Maritime
Corrosion protection performance is verified through standardized ASTM testing under ISO 9001 quality controls. Results are documented on your Certificate of Conformance for production traceability and warranty support.
4,000+ hours salt spray resistance
Validated against ASTM B117, the same standard used to evaluate coatings for saltwater service. For maritime equipment, this translates to years of protection on hardware facing continuous salt spray, immersion, and humid coastal conditions that destroy conventional coatings in months.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
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.
Yes. Engine mounts, transmission components, suspension bushings, and exhaust hangers experience constant vibration that can crack rigid coatings. Polymer coating provides corrosion and chemical protection while flexing with the component. For high-performance and racing applications, polymer coating protects components exposed to fuels, brake fluid, and coolant without adding significant weight. The coating maintains adhesion through thousands of thermal and vibration cycles.
Choose polymer coating when your parts experience significant flexing, vibration, thermal expansion cycling, or require chemical immersion resistance beyond what rigid ceramic coatings provide. Examples include flexible hoses, rubber-to-metal transitions, vibration-dampening mounts, and chemical tank internals. If your application demands hardness and abrasion resistance, Cerakote is the better choice. We evaluate your specific application and recommend the right coating, or combination, for the operating conditions.
Yes. Defense equipment may encounter fuels, hydraulic fluids, solvents, decontamination agents, and environmental chemicals. Polymer coatings provide broad chemical resistance with the flexibility to survive field handling, vibration, and thermal cycling. For defense hardware requiring both chemical resistance and abrasion protection, we may recommend polymer coating as a base layer with Cerakote topcoat. All defense coating work is performed under ITAR controls within our registered facility.
Raw AM parts have the gray, white, or metallic appearance of their base material, which is not acceptable for customer-facing or branded applications. Cerakote color matching transforms these parts to production-quality appearance with your specified color, verified to Delta E 1.5. Combined with the surface smoothing effect of Cerakote (reducing Ra from 8-15 micrometers to below 3 micrometers), color matching is the final step that bridges the gap between prototype appearance and production finish.
