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
The Cerakote catalog includes 200+ standard colors across gloss, matte, and satin finishes. Custom color matching to your Pantone reference, RAL number, or physical sample is available with a typical 5-7 business day development lead time. Once a custom color is validated and documented, it is repeatable to Delta E 1.5 on all future orders. Multi-color applications, patterns, and graphics are also achievable through precision masking techniques.
The 2-4 mil anchor profile created by blasting gives Cerakote mechanical interlocking sites across the entire substrate surface. On wear components subject to sliding contact, impact, or particle erosion, this mechanical bond keeps the coating in place under forces that would delaminate a coating applied to a smooth surface. Combined with Cerakote's 4,000 cycles per mil abrasion resistance, proper blast preparation delivers maximum wear life.
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.
AM-produced intake manifolds and plenums benefit from Cerakote's thermal barrier properties, reducing heat soak that increases intake air temperature and reduces engine performance. The ceramic-polymer coating applied at 0.5-2 mils provides measurable thermal insulation on thin-wall AM structures where traditional thermal wraps or coatings would add unacceptable weight and bulk. Combined with surface smoothing below Ra 3 micrometers for improved airflow, post-processed AM intakes outperform raw prints on both thermal management and flow efficiency.
Yes. Agricultural equipment operates in continuous moisture from irrigation, rain, and soil contact, often combined with road salt exposure during transport between fields. Polymer coating provides flexible corrosion protection that survives the vibration and impact of field operation. For equipment frames, mounting brackets, and structural components that flex under load, polymer coating maintains adhesion where rigid coatings develop stress cracks that allow moisture penetration and subsurface corrosion initiation.
