Corrosion Protection for Medical Devices
Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.
The Corrosion Problem in Medical Devices
Where sterilization is the corrosion accelerator
The challenge
Harsh environments demand coatings that hold.
The solution
ColoradoKote ceramic coating stops corrosion cold.
Why Cerakote for Medical Corrosion Protection
Survives sterilization, preserves instrument function
Sterilization-resistant corrosion barrier
4,000+ hours salt spray resistance (ASTM B117) combined with chemical resistance to autoclave steam, ethylene oxide, hydrogen peroxide plasma, and hospital-grade disinfectants. The coating maintains its protective barrier through hundreds of sterilization cycles without degradation, cracking, or particulate shedding.
Dimensional precision for surgical instruments
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. This is 60-75% thinner than powder coating at 3-5 mils, eliminating the rework caused by oversized coatings on precision instruments.
ISO 9001 traceability for device manufacturers
Every coating job is documented under ISO 9001:2015 quality controls. Certificate of Conformance includes coating thickness, adhesion results, and material batch records. Documentation supports device manufacturer quality system requirements. Regulatory compliance and biocompatibility validation remain the responsibility of the device manufacturer.
Multi-substrate instrument compatibility
Cerakote bonds to stainless steel and titanium, the two primary surgical instrument substrates. One coating process handles mixed-material instrument sets. Color-coded applications use the Cerakote catalog of 200+ colors for instrument identification that survives sterilization cycles.
Corrosion Specs for Medical Applications
How We Deliver Corrosion Protection for Medical
Controlled environment with documented traceability at every step
Medical Component Surface Preparation
Instruments are ultrasonically cleaned and degreased to remove all surface contaminants. Stainless steel and titanium substrates receive preparation methods matched to their alloy composition for maximum corrosion barrier adhesion. Masking protects cutting edges, jaw surfaces, and mating features that must remain uncoated.
Precision Corrosion Barrier Application
Cerakote is applied via calibrated HVLP equipment at 0.5-2 mil controlled thickness. In-process DFT measurement confirms dimensional compliance before curing at 250-300 F. Color-coded applications are verified by spectrophotometer for Delta E ≤1 consistency across instrument sets.
Quality Inspection and Documentation
Multi-point final inspection verifies coating thickness, adhesion per ASTM D3359, color consistency, and visual appearance under magnification. Certificate of Conformance documents all measurement data and material batch records. Documentation supports device manufacturer quality system and regulatory requirements.
Proven Corrosion Protection for Medical Devices
Corrosion protection performance is verified through standardized ASTM testing under ISO 9001 quality controls. Results are documented on your Certificate of Conformance for device manufacturer quality records and regulatory documentation.
4,000+ hours salt spray resistance
Validated against ASTM B117. For medical device applications, this corrosion resistance translates to long-term protection through hundreds of autoclave cycles and chemical sterilization exposures. The coating maintains barrier integrity and surface smoothness, reducing contamination risk from coating degradation.

Yes. Cerakote achieves 4,000 abrasion cycles per mil (ASTM D4060) and 9H pencil hardness (ASTM D3363), providing substantial resistance to particulate erosion on flow surfaces, choke components, and valve internals. For high-erosion applications, the combined stack of chemical conversion coating plus Cerakote provides both adhesion insurance and the hard ceramic wear surface needed to extend component service life in sand-producing wells.
Yes. Valve assemblies in oil and gas service frequently require color-coded markings for flow direction, service type, and maintenance status. We apply multi-color Cerakote with precision masking to maintain sharp boundaries between color zones. Each color is spectrophotometer-verified to Delta E 1.5 and cured separately. The 0.5-2 mil film build does not interfere with sealing surfaces or threaded connections, and the finish withstands the H2S, brine, and temperature cycling of field environments.
Passivation ensures the stainless substrate is clean and corrosion-resistant, while Cerakote provides a hard ceramic topcoat that resists scratching, abrasion, and impact. At 0.5-2 mils of Cerakote thickness, this stack handles wear far better than bare or passivated-only stainless while maintaining tight tolerances. For parts facing both corrosive environments and mechanical wear, this combination outperforms powder coating (4-6 mils) in both durability per mil and overall corrosion resistance.
We offer 14-day standard turnaround for passivation, with 7-day and 3-day expedited options for build deadlines and race season prep. For automotive projects using both stainless and aluminum components, we can passivate the stainless, apply chemical conversion coating to the aluminum, and Cerakote everything in a single facility. This single-source approach saves time and ensures finish consistency across mixed-material builds.
