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
We use controlled media blasting at 40 to 60 PSI, lower than our standard 80 to 100 PSI range, to remove support marks and reduce surface roughness on AM parts without compromising dimensional accuracy. For metal AM parts, we follow blasting with passivation or chemical conversion as appropriate for the substrate. This multi-step preparation ensures Cerakote achieves full adhesion and a uniform finish.
Yes. Every order ships with a Certificate of Conformance documenting coating formulation, lot traceability, thickness measurements, adhesion results, and cure parameters. Our AS9100 quality system generates documentation that meets aerospace and defense requirements, but we provide certificates for all orders regardless of industry. Custom documentation formats and additional test reports are available upon request.
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.
Cerakote applies at 0.5-2.0 mils (12.7-50.8 microns), controlled by in-process DFT gauge measurements. This thin-film application preserves dimensional tolerances on precision components, interference-fit fasteners, and close-tolerance assemblies. By comparison, powder coating adds 4-6 mils and frequently causes dimensional issues requiring post-coating machining. We mask threaded holes, bearing surfaces, and critical datum features to maintain your specified dimensions exactly.
Yes. We coat SLS nylon (PA12, PA11), MJF polymer parts, and metal additive builds including titanium and stainless steel. Cerakote bonds chemically to these substrates without dimensional distortion, adding only 0.5-2 mils of thickness. For polymer AM parts, the coating also reduces surface roughness and provides corrosion and chemical resistance not achievable with raw printed surfaces. Current capacity is 200 AM parts per week with 7-10 day standard turnaround.
