Corrosion Protection for Automotive R&D
Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.
The Corrosion Problem in Automotive R&D
Prototypes must pass production-grade testing
The challenge
Harsh environments demand coatings that hold.
The solution
ColoradoKote ceramic coating stops corrosion cold.
Why Cerakote for Automotive Corrosion Protection
Production-grade protection on prototype timelines
Salt spray performance that passes validation
4,000+ hours salt spray resistance (ASTM B117) gives prototypes the corrosion data needed for engineering validation sign-off. This exceeds anodizing (336-1,000 hours) and powder coating performance, providing margin for accelerated cyclic testing and under-hood chemical exposure evaluations.
Thin-film weight advantage at 0.5-2 mils
Every gram matters in EV range calculations. Cerakote adds 0.5-2 mils versus 3-5 mils for powder coating, resulting in 200-400 g less weight per component. Across a prototype with 200 or more coated parts, the savings reach pounds of total coating weight that directly affects range estimates.
Documented results for engineering review
Certificate of Conformance includes coating thickness, adhesion data, and color measurements verified by spectrophotometer. ISO 9001 quality controls ensure consistent, traceable results that satisfy engineering validation requirements. Documentation supports test data packages for program milestones.
Multi-substrate coverage from one source
Carbon fiber, aluminum, titanium, steel, and 3D-printed metal components all receive corrosion protection from one coating partner. Color consistency at Delta E ≤1 across all substrates eliminates visible variation on prototype assemblies. One vendor replaces four to six material-specific coating suppliers.

How We Deliver Corrosion Protection for Automotive
Multi-substrate process built for prototype speed and R&D deadlines
Multi-Substrate Assessment and Preparation
Parts arrive and our team evaluates each substrate material for corrosion protection requirements. Carbon fiber receives light scuff sanding and ultrasonic cleaning. Aluminum undergoes MIL-DTL-5541 conversion coating for enhanced adhesion. Titanium and steel follow tailored blasting profiles. Masking protects critical surfaces and mating areas across all materials in the batch.
Corrosion Barrier Coating Application
Cerakote is applied at 0.5-2 mil thickness via calibrated HVLP equipment, building a uniform corrosion barrier across all substrate types. Color is verified by spectrophotometer to maintain Delta E ≤1 consistency between carbon fiber panels and metal enclosures. In-process DFT measurements confirm thickness on every part.
Curing and Validation Documentation
Parts cure at 250-300 F in temperature-controlled ovens, below the post-cure threshold for carbon fiber composites. Final inspection verifies thickness, adhesion, and color consistency. Certificate of Conformance documents all measurements for engineering validation review. Expedited options are available for auto show and milestone deadlines.
Proven Corrosion Protection for Automotive R&D
Corrosion protection performance is verified through the same standardized ASTM testing used in automotive validation programs. Results are documented under ISO 9001 quality controls and included on your Certificate of Conformance for engineering review.
4,000+ hours salt spray resistance
Validated against ASTM B117, the standard referenced in automotive accelerated corrosion testing protocols. This performance provides margin above typical validation requirements, reducing the risk of re-testing delays that push prototype deadlines. Results apply across all substrate materials in your prototype assembly.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Yes. Complex internal passages, including cross-drilled holes, cooling channels, manifold circuits, and flow paths, are exactly where ultrasonic cleaning excels. Cavitation occurs wherever the cleaning solution reaches, providing uniform cleaning action inside passages that manual methods, spray systems, and even high-pressure flush cannot effectively clean. This capability is critical for industrial components where internal cleanliness directly affects function and coating quality.
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.
Every Cerakote job at ColoradoKote is tracked under our AS9100:2015 quality management system with full material batch numbers, application parameters, cure profiles, and inspection data. Parts ship with a Certificate of Conformance documenting coating thickness (0.5-2 mils), adhesion, color consistency (Delta E 1.5), and all process variables. This level of documentation satisfies aerospace OEM and Tier 1 supplier quality requirements, including those we maintain for multiple manufacturers.
Cerakote acts as an electrical insulator between dissimilar metals, breaking the galvanic circuit that drives accelerated corrosion at material interfaces. Dielectric strength of 3,000 volts per mil (H-900 series) provides substantial electrical isolation. This is particularly valuable on assemblies combining aluminum with steel, titanium with stainless, or any multi-material design where galvanic corrosion would otherwise require sacrificial anodes or isolation washers.
Yes. Cerakote bonds to all metals (aluminum, steel, titanium, stainless, Inconel) and polymers (PA12, PA11, and other engineering plastics). Surface preparation is tailored to each substrate type within the same production order. This is a significant advantage over anodizing (aluminum only) and electroplating (metals only). Mixed-substrate orders are common in our additive manufacturing and industrial work.
