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
Clean substrate surfaces are the foundation for all downstream AM post-processing. Residual powder, oils from handling, and manufacturing residue create adhesion failures and surface defects in the finished coating. Ultrasonic cleaning integrated into the AM post-processing sequence, before blasting and coating, ensures every part starts from a verified-clean condition. This contributes to the consistent quality results that allow us to maintain our 20,000+ parts track record with zero quality issues.
Ship parts clean and dry, packaged to prevent damage in transit. Remove any loose debris or excessive contamination, but do not attempt to blast or chemically treat parts before shipping, as our surface preparation process is calibrated to specific substrates and Cerakote requirements. Include your engineering drawings, specification callouts, and any masking requirements with the shipment. We handle all preparation from receiving inspection through coating under our AS9100 process controls.
Yes. Oil and gas components often receive multi-layer coating systems including passivation followed by Cerakote, or polymer coating for chemical resistance with Cerakote topcoat for abrasion protection. Ultrasonic cleaning before each coating layer ensures contamination-free interfaces between layers. This inter-layer cleanliness prevents delamination at coating boundaries under the thermal cycling and pressure conditions of oil and gas service, maximizing the performance of the complete coating stack.
Every ounce matters in aerospace. Cerakote's 0.5 to 2 mil film build versus powder coat's 4 to 6 mils reduces coating weight by 50 to 85 percent across thousands of cabin interior components, brackets, and fixtures. This weight reduction translates directly to fuel savings over the operational life of the aircraft. The thinner film also preserves critical tolerances on seat mechanisms, latch hardware, and precision-fit components.
Yes. We run the complete preparation-to-coating sequence in-house: ultrasonic cleaning removes machining fluids and contaminants from blind holes and internal passages, chemical conversion coating (chromate or non-chromate) provides the adhesion-promoting base layer, and Cerakote ceramic coating delivers the final corrosion and wear barrier. Running this full stack under one AS9100 quality system eliminates handoff risk between multiple vendors and compresses your lead time.
