ColoradoKote ceramic coating stops corrosion cold.
Why ColoradoKote Ultrasonic for Aerospace
Contamination-free surfaces verified before coating
Complete contaminant removal from complex geometries
40 kHz cavitation reaches blind holes, internal threads, and recessed features that manual solvent wipes miss entirely. Aerospace cabin hardware, structural fasteners, and engine components all contain geometries where oils and particulates accumulate during manufacturing. Ultrasonic cleaning removes these contaminants uniformly on every part, every cycle, eliminating the operator variability that causes inconsistent surface preparation.
Oil bleed-out prevention for cabin parts
Trapped machining fluids and lubricants migrate through coating films over time, causing blistering and delamination weeks or months after installation. This failure mode is particularly damaging on visible cabin interior hardware where appearance and durability both matter. Ultrasonic cavitation extracts embedded oils from surface pores that manual cleaning leaves behind, preventing post-installation coating failures.
ASTM D3359 5B adhesion verified
Coated parts that begin with ultrasonic cleaning consistently achieve ASTM D3359 5B adhesion ratings, the highest grade on the cross-cut adhesion scale, with zero coating removal. This adhesion performance is the direct result of contamination-free surfaces verified through water-break testing before coating application. Every adhesion test result is documented on your Certificate of Conformance.
AS9100 cleaning validation on every batch
Every cleaning cycle is recorded with solution type, concentration, temperature, frequency, cycle duration, and verification results. Solution concentration is monitored through weekly titration testing. Equipment calibration follows documented schedules. Your auditors receive objective quality evidence showing that surface preparation met specification before coating began, per AS9100:2015 requirements.

How We Clean Aerospace Parts
AS9100 documented from contamination assessment through coating handoff
Contamination Assessment and Solution Selection
Technicians assess each aerospace part for contamination type: machining fluids, fingerprint oils, lubricant residue, or embedded particulates. Substrate material determines solution chemistry. Alkaline cleaners address aluminum alloys. Neutral formulations protect titanium from hydrogen embrittlement. Temperature is set between 120-160 F and cycle time between 10-30 minutes based on contamination severity. Masking protects any features that must remain uncoated.
40 kHz Ultrasonic Cavitation
Parts are submerged in heated cleaning solution and the 40 kHz transducer activates. Millions of cavitation bubbles form and implode against every surface, penetrating blind holes, internal threads, and complex recesses. A minimum of two DI water rinses follow the cleaning cycle, removing all solution residue. Heated air drying or nitrogen purge prepares parts for immediate coating application, preventing re-contamination from environmental exposure.
Verification and Documented Handoff
Water-break testing confirms DI water sheets uniformly across the surface with no beading, verifying the absence of oils and residues. White-glove inspection checks for particulate transfer. Parts that do not pass verification are re-cleaned before proceeding. Verified parts transfer immediately to coating application. Process parameters from the cleaning cycle are recorded in the batch traveler and integrated with the coating record for complete AS9100 traceability.
Proven Surface Preparation for Aerospace
Surface preparation performance is verified through standardized adhesion testing on coated parts, not subjective visual inspection. Every production batch undergoes the same cleaning verification and post-coating adhesion testing under AS9100 controls, with results documented on your Certificate of Conformance.
ASTM D3359 5B adhesion rating
5B is the highest grade on the ASTM D3359 cross-cut adhesion scale, indicating zero coating removal during testing. Parts that begin with ultrasonic cleaning consistently achieve this rating because contaminants that cause adhesion failure have been removed and verified absent before coating begins. The 80% of coating failures that trace to poor surface preparation are eliminated at the source, before a single drop of coating is applied.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Yes. Abrasion resistance of 4,000 cycles per mil (ASTM D4060) and 9H pencil hardness (ASTM D3363) provide substantial protection against the grinding abrasion of soil, sand, and crop material on coulter blades, seed openers, ground-engaging tools, and conveyor surfaces. For high-wear components, the full stack of chemical conversion coating plus Cerakote maximizes adhesion so the coating stays bonded under sustained abrasive contact.
Cerakote application does not introduce hydrogen into the substrate, unlike electroplating processes that carry embrittlement risk on high-strength steels (above Rockwell C 39). Surface preparation uses media blasting at 80-100 PSI rather than acid pickling, further eliminating hydrogen exposure. This makes Cerakote a safer alternative to chrome and cadmium plating on critical oilfield components where embrittlement-induced failure is a safety concern.
Yes. Raw AM parts, particularly polymer SLS and MJF builds, have surface and near-surface porosity that allows moisture and chemical ingress. Cerakote fills and seals these pores during application, creating a continuous barrier layer at 0.5-2 mils thickness. This sealing effect provides corrosion protection exceeding 3,000 hours salt spray on metal AM parts and chemical resistance on polymer AM parts that raw printed surfaces cannot achieve.
Cerakote applies at 0.5-2 mils versus 4-6 mils for powder coating, preserving the fine detail and edge definition on machined or forged wheels. Color consistency at Delta E 1.5 is tighter than powder coating's typical Delta E 2-4, and salt spray resistance of 3,000 hours (ASTM B117) versus 500-1,500 hours for powder coating means better protection against road salt and brake fluid. Cerakote also resists chipping 2-3 times better than powder coating.
Yes. Cerakote's temperature range from -40 degrees F to 2,000 degrees F covers the thermal extremes encountered in downhole service. The coating maintains adhesion through the pressure cycling and thermal shock conditions of wellbore operations. For AM parts with their inherent porosity, the sealed Cerakote barrier is especially critical because pressure-driven fluid ingress through surface pores would undermine the part's structural integrity. Sealing plus protection makes AM viable for downhole deployment.
