Aesthetic Finishing for Medical Devices
Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.
The Color Problem in Medical Instruments
Where sterilization destroys identification
The challenge
Harsh environments demand coatings that hold.
The solution
ColoradoKote ceramic coating stops corrosion cold.
Why Cerakote for Medical Device Aesthetics
Color coding that survives sterilization
Delta E ≤1 across instrument sets
Spectrophotometer-verified color accuracy ensures every instrument in a set matches, and replacement instruments match the original set color years later. Locked inorganic pigment formulas resist degradation from autoclave steam, ethylene oxide, and hydrogen peroxide plasma through hundreds of sterilization cycles.
Thin-film finish preserving instrument precision
0.5-2 mil coating thickness preserves the dimensional tolerances critical to surgical instrument function. Jaw closures, cutting edges, and mating surfaces maintain their engineered geometry after coating. Powder coating at 3-5 mils alters instrument dimensions and fails functional testing.
ISO 9001 color and process documentation
Certificate of Conformance documents spectrophotometer readings, Delta E measurements, coating thickness, and material batch records for every production lot. ISO 9001 traceability supports device manufacturer quality system requirements and regulatory documentation needs.
200+ colors for medical identification
The Cerakote catalog includes the full range of colors used for instrument set identification, specialty coding, and size differentiation. Multi-substrate compatibility means stainless steel and titanium instruments coat to the same color standard. Chip resistance 2-3 times superior to powder coating prevents particulate generation in sterile environments.

How We Deliver Aesthetic Finishing for Medical
Controlled color application for instrument identification
Instrument Assessment and Surface Preparation
Stainless steel and titanium instruments receive preparation methods matched to their alloy composition. Ultrasonic cleaning removes contaminants, followed by degreasing and tailored media blasting. Masking protects cutting edges, jaw surfaces, and mating features that must remain uncoated to preserve instrument function.
Color-Coded Cerakote Application
Cerakote is applied via calibrated HVLP equipment at 0.5-2 mil thickness with in-process DFT measurement. The locked color formula ensures set-to-set consistency verified by spectrophotometer. Cure temperature of 250-300 F is compatible with common medical device substrates and does not alter instrument heat treatment.
Inspection and Quality Documentation
Final inspection verifies coating thickness, adhesion per ASTM D3359, and spectrophotometer-confirmed Delta E ≤1 color accuracy across the instrument set. Certificate of Conformance documents all measurements and material batch records. Documentation supports device manufacturer quality system requirements.
Proven Color Durability for Medical Instruments
Color performance is verified through spectrophotometric measurement on every production batch under ISO 9001 quality controls. Results are documented on the Certificate of Conformance. Biocompatibility validation remains the responsibility of the device manufacturer.
Delta E ≤1 color consistency
Maintained across stainless steel and titanium instrument substrates using inorganic pigments resistant to autoclave steam and chemical sterilants. Combined with 9H pencil hardness, the finish resists both color degradation and physical chipping through hundreds of sterilization cycles, maintaining instrument identification throughout service life.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
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.
Defense AM parts face salt spray, sand abrasion, chemical exposure, and temperature extremes from -40 degrees F to elevated operating temperatures. Cerakote provides a combined defense: salt spray resistance exceeding 3,000 hours, abrasion resistance of 4,000 cycles per mil, chemical resistance across the pH spectrum, and thermal stability. Applied at 0.5-2 mils over properly prepared AM surfaces, Cerakote transforms vulnerable raw AM parts into field-ready defense components.
Yes. Multiple layers of marine paint, antifouling coatings, and zinc-rich primers create complex contamination that must be fully removed before applying new protective coatings. Ultrasonic cavitation assists chemical stripping by driving cleaning solution into the coating layer interfaces and substrate surface, ensuring complete removal of all old coating material. This thorough removal is critical because residual old coating prevents adhesion of the new Cerakote system and traps corrosion-initiating contaminants against the substrate.
We verify cleanliness using multiple methods scaled to the application criticality. Water-break testing confirms surfaces are free of oils and films when deionized water sheets uniformly without beading. White-glove inspection detects particulate contamination. For critical aerospace applications, dyne pen testing measures surface energy against your specified threshold. Rinse water conductivity below 10 microsiemens per centimeter confirms rinse effectiveness. Any part failing verification is re-cleaned before proceeding.
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.
