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.

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.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
We passivate defense stainless steel components to ASTM A967 and AMS 2700 with full lot traceability and documentation. The process removes free iron and contaminants without any dimensional change, which is critical for weapon system fittings, fasteners, and structural hardware. Our facility has processed over 20,000 parts with zero quality issues, and our documentation packages meet the traceability requirements that defense programs require.
Yes. AM already enables weight-optimized geometries through topology optimization and lattice structures. Cerakote at 0.5-2 mils preserves this weight advantage while adding protection, unlike powder coat at 4-6 mils or multi-layer paint systems that add measurable weight. For racing applications where every gram matters, the AM-plus-Cerakote combination delivers both geometry optimization and surface protection at minimum weight. The thin film build also maintains the dimensional precision of aerodynamic and performance-critical surfaces.
We coat steel, stainless steel, aluminum, titanium, copper alloys, and polymer substrates with corrosion-resistant Cerakote formulations. Each substrate receives appropriate preparation: chemical conversion for aluminum, passivation for stainless steel, and media blasting for ferrous metals and other materials. This multi-substrate capability means one vendor handles your full parts list regardless of material mix.
Yes. Engine bay components face operating temperatures, oil exposure, coolant contact, and road salt that would rapidly degrade raw AM surfaces. Cerakote H-Series provides chemical resistance and temperature stability for under-hood AM parts, while V-Series extends protection to exhaust-temperature applications up to 2,000 degrees F. Our 40-60 PSI blasting prepares AM surfaces without distorting the thin walls and complex geometries that make additive manufacturing valuable for automotive performance applications.
Raw AM parts typically exhibit Ra 8-15 micrometers depending on build orientation and process. Our post-processing sequence, controlled blasting at 40-60 PSI followed by Cerakote application at 0.5-2 mils, reduces surface roughness to below 3 micrometers. This transformation converts rough, porous AM surfaces into smooth, sealed, production-quality finishes with the added benefits of corrosion protection exceeding 3,000 hours salt spray and abrasion resistance of 4,000 cycles per mil.
