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. Raw AM parts with Ra 8-15 micrometers are not suitable for marine hardware that must resist biofouling, facilitate cleaning, and present a professional appearance. Our post-processing reduces surface roughness below 3 micrometers, creating a smooth surface that resists marine growth adhesion and cleans easily. Combined with corrosion protection exceeding 3,000 hours salt spray, this surface transformation makes AM a viable manufacturing path for marine hardware that previously required conventional production methods.
ColoradoKote routinely coats electronics enclosures, RF housings, and connector shells for defense programs. Cerakote's thin film build of 0.5 to 2 mils maintains critical tolerances on mating surfaces and connector interfaces that powder coat's 4 to 6 mils would compromise. Our passivation and chemical conversion capabilities let us prep stainless steel and aluminum housings in-house before topcoating.
At 0.5-2 mils thickness, Cerakote preserves interference fits and thread engagement that powder coating at 4-6 mils cannot maintain. We mask threaded holes, bearing surfaces, and critical datum features per documented masking plans reviewed against your engineering drawings. Over 20,000 parts coated with zero quality issues demonstrates the process control needed for precision aerospace hardware.
Cerakote's 0.5 to 2 mil film build versus powder coat's 4 to 6 mils reduces coating weight by over 50 percent without sacrificing protection. For industrial equipment where coating adds up across hundreds of components, this difference reduces finished assembly weight. The thinner film also preserves clearances on hydraulic cylinders, actuator housings, and precision-fit components that powder coat buildup can compromise.
Polymer coatings apply at thin film builds comparable to Cerakote, adding minimal weight compared to heavy rubber linings, multi-coat paint systems, or thick epoxy coatings traditionally used for chemical resistance. For aerospace and defense applications where weight is critical, polymer coating provides chemical and flex protection at a fraction of the weight of traditional flexible barrier coatings. This weight advantage is especially valuable when combined with Cerakote topcoat in a lightweight multi-layer system.
