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.

Advantages

Why Cerakote for Maritime Corrosion Protection

Built to resist continuous saltwater exposure

Placeholder image

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

One

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.

Compressed air cleaning
Two

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.

Coating application
Three

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.

Evidence

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

What turnaround options does ColoradoKote offer for automotive stainless passivation?

We offer 14-day standard turnaround for passivation, with 7-day and 3-day expedited options for build deadlines and race season prep. For automotive projects using both stainless and aluminum components, we can passivate the stainless, apply chemical conversion coating to the aluminum, and Cerakote everything in a single facility. This single-source approach saves time and ensures finish consistency across mixed-material builds.

How does custom color help with medical device identification?

Color coding is widely used in medical devices for instrument identification, size differentiation, and sterile versus non-sterile designation. Cerakote provides durable color that withstands autoclave sterilization cycles without fading, chipping, or color shift. We match your specified identification colors to Delta E 1.5 and verify consistency across production lots so that color-coded instruments remain reliably identifiable throughout their service life.

How does ColoradoKote maintain color consistency across large aerospace orders?

Color consistency on large aerospace programs requires controlled material batches, documented application parameters, and spectrophotometer verification on every production lot. We record coating material lot numbers, spray parameters, cure profiles, and Delta E measurements as part of our AS9100 quality system. This documentation ensures that parts produced on day one of a multi-month program match parts produced on the final day, verified by instrument, not visual judgment alone.

Does ultrasonic cleaning support requalification of returned oil and gas tools?

Yes. Downhole tools returned from service carry production chemicals, scale, and corrosion products that must be completely removed before inspection and recoating. Ultrasonic cavitation reaches contaminants in thread roots, seal grooves, and internal flow passages that determine tool serviceability. Verified cleanliness after ultrasonic processing allows accurate inspection of the substrate condition and ensures that reapplied Cerakote bonds properly for the tool's next deployment in corrosive downhole environments.

How does ColoradoKote support aerospace refurbishment cycles?

Cerakote's 3,000-hour salt spray performance and 4,000 cycles per mil abrasion resistance significantly extend the interval between refurbishment cycles on cabin interiors and high-touch components. Thinner film builds of 0.5 to 2 mils versus 4 to 6 mils for powder coat preserve critical tolerances on seat mechanisms and galley hardware. Longer part life means fewer removals, less downtime, and lower lifecycle cost for fleet operators.
