The solution
ColoradoKote ceramic coating stops corrosion cold.
Why ColoradoKote Cerakote for AM Production
Protection and precision that alternatives cannot match
Surface roughness reduction with functional protection
Cerakote fills micro-voids and smooths layer lines, reducing surface roughness from Ra 8-15 micrometers to below 3 micrometers measured by stylus profilometer. Unlike vapor polishing and tumbling, which remove material without adding any barrier, Cerakote simultaneously delivers corrosion resistance (3,000+ hours ASTM B117 on metal AM), 8H-9H pencil hardness (ASTM D3363), and 100+ color options. One coating step replaces three separate finishing operations.
Dimensional tolerance preservation at 0.5-2 mils
Thin-film application adds only 0.001 to 0.002 inches per coated surface. Parts remain within the plus or minus 0.005 inch tolerance envelope, verified by CMM measurement on every production batch. Powder coating at 3-5 mils pushes AM parts outside tolerance, requiring post-machining that eliminates topology-optimized features. Cerakote eliminates that rework entirely.
Material-specific protocols for every AM substrate
PA12 and MJF nylon receive fine glass bead blasting at 40-50 PSI to preserve thin walls. Ti-6Al-4V receives controlled aluminum oxide blasting at 50-60 PSI with cure profiles validated to prevent embrittlement. AlSi10Mg, Inconel, and 316L stainless each follow separate preparation sequences. Generic coating shops treat all AM parts identically, damaging thin-walled polymer structures and wasting expensive metal builds.
200 AM parts per week with certified traceability
Dedicated AM post-processing capacity processes 200 parts per week with standard turnaround of 7-10 business days and expedited service at 3-4 business days. Every order ships with a Certificate of Conformance documenting surface roughness data, dimensional verification, material batch records, and cure parameters. AS9100 documentation is available for aerospace AM applications, and ITAR registration covers defense AM work.

How We Apply Cerakote to AM Parts
Material-specific preparation protocols for polymer and metal additive manufacturing
Substrate Assessment and Surface Preparation
Every AM part is identified by material and build technology: PA12 (SLS), PA11, MJF nylon, Ti-6Al-4V (PBF-LB), AlSi10Mg, Inconel, or 316L stainless. Polymer parts receive fine glass bead blasting at 40-50 PSI to create an adhesion profile without distorting thin walls or lattice structures. Metal AM parts receive aluminum oxide blasting at 50-60 PSI with focused attention on support structure contact areas. Ultrasonic cleaning removes residual blast media and powder particles trapped in surface pores.
Calibrated Thin-Film Application
Cerakote is applied via calibrated HVLP equipment at 0.5-2 mil thickness, monitored in-process with DFT gauges. Tight-tolerance parts receive 0.5-1.0 mil application to maximize dimensional preservation. Cosmetic-priority parts receive up to 2.0 mils for maximum surface smoothing. Polymer substrates cure at 250 F, below PA12 heat deflection temperature, to prevent warping. Metal AM substrates follow standard cure profiles at 250-300 F. Climate-controlled spray booth monitors temperature within plus or minus 5 F and humidity within plus or minus 10% throughout application.
Dimensional Verification and Quality Documentation
Post-coating CMM measurement confirms parts remain within the plus or minus 0.005 inch tolerance envelope. Stylus profilometer verifies surface roughness reduction to below Ra 3 micrometers. Adhesion testing per ASTM D3359 and DFT thickness measurement complete the inspection sequence. Every order ships with a Certificate of Conformance including before-and-after Ra data, dimensional verification, material batch records, and cure parameters. AS9100 first article inspection reports are available for aerospace AM programs.
Proven Cerakote Performance on AM Parts
AM post-processing performance is verified through dimensional measurement and standardized ASTM testing, not manufacturer claims. ColoradoKote documents before-and-after results on every production batch under AS9100 and ISO 9001 controls, and all data ships on your Certificate of Conformance.
Plus or minus 0.005 inch tolerance maintained
CMM measurement confirms that Cerakote application at 0.5-2 mils adds only 0.001 to 0.002 inches per coated surface, keeping AM parts within their designed tolerance envelope. Powder coating at 3-5 mils causes dimensional interference that requires post-machining, eliminating the cost and lead time advantages of additive manufacturing. ColoradoKote has maintained this tolerance standard across PA12, PA11, Ti-6Al-4V, AlSi10Mg, and Inconel substrates at production volumes of 200 parts per week.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Yes. Cerakote at 0.5-2 mils adds approximately 0.001 to 0.003 ounces per square inch, negligible compared to traditional coatings. This is critical for aerospace AM parts where the entire point of additive manufacturing is weight optimization through topology and lattice design. Adding a heavy coating would negate the weight savings from AM. Cerakote preserves the weight advantage while delivering salt spray resistance exceeding 3,000 hours and abrasion resistance of 4,000 cycles per mil.
Every production lot undergoes multi-point inspection: coating thickness verified by calibrated DFT gauge against the 0.5-2 mil specification, adhesion tested per ASTM D3359, color consistency measured by spectrophotometer to confirm Delta E 1.5 or better, and visual inspection against documented acceptance criteria. Results are recorded on the Certificate of Conformance that ships with every order. Additional testing including salt spray and pencil hardness is available per purchase order requirements.
Passivation restores the stainless steel's natural chromium oxide barrier, and adding Cerakote extends corrosion protection to 3,000 hours of salt spray resistance (ASTM B117). This combined stack provides a dual barrier against the chloride attack, H2S exposure, and erosion common in sour gas and offshore environments. At just 0.5-2 mils of Cerakote over the passivated surface, the total buildup is minimal compared to traditional protective coating systems.
Yes. We coat SLS nylon (PA12, PA11), MJF polymer parts, and metal additive builds including titanium and stainless steel. Cerakote bonds chemically to these substrates without dimensional distortion, adding only 0.5-2 mils of thickness. For polymer AM parts, the coating also reduces surface roughness and provides corrosion and chemical resistance not achievable with raw printed surfaces. Current capacity is 200 AM parts per week with 7-10 day standard turnaround.
Cerakote's ceramic-polymer matrix is chemically inert once cured, and specific formulations have been evaluated for biocompatibility in device applications. The coating resists autoclave sterilization cycles, chemical disinfectants, and repeated cleaning without degradation. ColoradoKote applies Cerakote under ISO 9001:2015 process controls with full lot traceability, providing the documentation framework medical device manufacturers require for regulatory submissions.
