Weight Reduction

Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.

The cost

What Thick Coatings Cost Your Lightweighting Program

Every gram removed through topology optimization, material substitution, or additive manufacturing represents engineering investment. A 4-6 mil powder coating adds that weight back, consuming dimensional tolerance budgets and compounding across production volumes. For aerospace fleets, the penalty multiplies across hundreds of aircraft and thousands of flight hours.

  • Tolerance consumed: Powder coating at 3-5 mils adds up to 0.003 inches per side, exceeding tight-tolerance budgets on precision mating surfaces and threaded features
  • Weight compounding: Across 5,000 coated interior components per aircraft, thick coatings add 156 lbs versus 37.5 lbs with thin-film application, a 118.5 lb penalty per airframe
  • Interference fits: Complex AM geometries, lattice structures, and conformal cooling channels clog or bridge when coated at 4+ mils, requiring rework or scrapping optimized parts

The answer

Thin-Film Ceramic Coating at 0.5-2 Mils

Cerakote® ceramic coating bonds at the molecular level in a 0.5-2 mil film, delivering full corrosion and wear protection without measurable weight penalty. The thin-film application conforms to complex geometries, preserves dimensional tolerances to within 0.001 inches, and maintains performance that thick coatings require 3-5 mils to achieve.

  • 200-400g savings per part: At 0.5-2 mils versus powder coating at 3-5 mils, each component carries a fraction of the coating weight while retaining 3,000+ hours of salt spray resistance (ASTM B117)
  • Tolerance preservation: A 1 mil application adds only 0.001 inches per side, maintaining thread class fit and press-fit dimensions that powder coating destroys at 4+ mils
  • Complex geometry conformance: Thin-film coating follows lattice structures, topology-optimized features, and internal channels without bridging or clogging passages critical to AM part function

Measured Thickness, Verified Weight Savings

Every weight reduction claim is verified through dry film thickness measurement (ASTM B499), pre- and post-coating dimensional inspection, and gravimetric analysis. AS9100 documentation captures coating thickness, dimensional data, and weight calculations for each production lot.

  • Coating thickness: 0.5-2.0 mils measured via magnetic induction and eddy current methods per ASTM B499, with uniformity of 0.0002 inches on flat surfaces and 0.0005 inches on complex geometries
  • Dimensional verification: Pre- and post-coating CMM measurement confirms tolerance preservation, with AS9102 First Article Inspection available for aerospace programs
  • Full protection at thin film: 3,000+ hours salt spray resistance (ASTM B117), 9H pencil hardness (ASTM D3363), and 8,000+ wear cycles per mil (ASTM D4060), all achieved at 0.5-2 mils

Frequently Asked Questions

Find answers about our coating processes and technical capabilities

What defense applications does ColoradoKote support?

ColoradoKote is ITAR registered and coats weapons system components, electronics housings, vehicle-mounted hardware, and field-deployed equipment for defense programs. Our facility in Johnstown, CO maintains the security protocols and documentation controls required for controlled technical data. We offer low-visibility finishes in earth tones, flat blacks, and custom tactical colors matched to program specifications.

How long does passivation protect stainless steel from corrosion?

The corrosion protection from passivation is inherent to the stainless steel itself. By removing contaminants and maximizing surface chromium, passivation restores the material to its designed corrosion resistance, which can last the lifetime of the part in appropriate environments. For environments that exceed stainless steel's natural limits, adding a Cerakote topcoat at 0.5-2 mils extends measurable salt spray resistance to 3,000 hours per ASTM B117.

What chemical resistance does polymer coating provide for industrial applications?

Polymer coatings resist a broad range of acids, bases, solvents, petroleum products, and process chemicals encountered in industrial environments. The specific chemical resistance profile depends on the polymer formulation selected for your application. We evaluate your chemical exposure conditions and select the formulation that provides the required resistance. For chemical tank internals, pipe fittings, and valve components, polymer coating provides flexible protection that survives thermal cycling and vibration.

How does Cerakote compare to vapor smoothing for AM post-processing?

Vapor smoothing works only on specific polymer AM materials and offers no protective properties, just surface smoothing. Cerakote post-processing reduces surface roughness from Ra 8-15 micrometers to below 3 micrometers while simultaneously adding corrosion protection exceeding 3,000 hours salt spray, abrasion resistance of 4,000 cycles per mil, and chemical resistance. Cerakote also works on both polymer and metal AM substrates, making it a universal post-processing solution that vapor smoothing cannot match in scope or performance.

Does blasting help improve the surface finish on 3D-printed parts?

Yes. Raw AM parts typically exhibit Ra 8-15 micrometers depending on build orientation and technology. Controlled blasting at 40-60 PSI knocks down the highest peaks and partially trapped powder, creating a more uniform surface for coating. When followed by Cerakote application, the combined process brings surface roughness below 3 micrometers. This makes blasting plus coating the most effective surface finishing path for production AM parts.
