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
Threaded connections and seal surfaces on oil and gas tools accumulate pipe dope, wellbore deposits, and corrosion products in thread roots and seal grooves that compromise connection integrity and coating adhesion. Ultrasonic cavitation at 40 kHz penetrates these tight geometries, dissolving and dislodging contaminants that brushing and spray cleaning cannot reach. For tools being recoated, verified thread cleanliness is essential for both coating performance and the mechanical reliability of make-up connections.
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.
Yes. ColoradoKote is registered with the Directorate of Defense Trade Controls (DDTC) under ITAR. Our facility, personnel, and processes meet all requirements for handling defense-related components and technical data. ITAR registration operates alongside our AS9100:2015 and ISO 9001:2015 certifications, so defense projects receive the same documented quality controls as our aerospace production work.
Each AM medical device order ships with a Certificate of Conformance documenting coating formulation, lot traceability, thickness measurements, adhesion results, and surface finish verification. Our ISO 9001:2015 quality system maintains controlled records that support FDA 21 CFR Part 820 and EU MDR requirements. For AM-specific documentation, we also record the incoming part condition, blast parameters at 40-60 PSI, and before/after surface roughness measurements to provide complete post-processing traceability.
Passivation per ASTM A967 / AMS 2700 removes free iron and surface contaminants from stainless steel through a controlled acid bath, bringing chromium to the surface to form a robust passive oxide layer. This restored passive layer is what gives stainless steel its corrosion resistance. The process adds no dimensional change, making it suitable for precision components. For maximum protection, passivation followed by Cerakote delivers 3,000 hours of salt spray resistance (ASTM B117).
