Why Cerakote for AM Weight Reduction

Thin-film protection built for printed geometries

200-400g savings per printed part

Cerakote at 0.5-2 mils replaces powder coating at 3-5 mils, preserving the mass savings that topology optimization and lattice structures deliver. On PA12 MJF brackets and metal AM housings alike, the thin film adds protection without measurable weight penalty relative to uncoated part weight.

Complex geometry conformance

Thin-film application follows lattice structures, conformal cooling channels, and topology-optimized features without bridging or material buildup. Internal passages remain open. Fine features remain defined. The coating conforms to the geometry rather than obscuring it, preserving the functional advantages of additive design.

Full AS9100 documentation for AM programs

Certificate of Conformance includes DFT measurements, material batch records, cure parameters, and pre- and post-coating weight data. Aerospace AM programs receive AS9100-compliant documentation with First Article Inspection reports available upon request. ITAR registration covers defense AM components.

Multi-material compatibility

One coating process covers PA12, PA11, glass-filled nylon, Ti-6Al-4V, AlSi10Mg, Inconel, and stainless steel. Mixed-material AM assemblies coat under a single work order with consistent thickness and weight documentation across all substrates, simplifying supply chain management for multi-material builds.

How We Deliver Weight Reduction for AM Parts

Material-specific protocols that preserve printed geometry and minimize mass

One

Material Assessment and Surface Preparation

Each AM part is identified by substrate: PA12, PA11, Ti-6Al-4V, AlSi10Mg, or Inconel. Polymer parts receive low-pressure aluminum oxide blasting at 30-40 PSI to prepare the surface without distorting thin walls or lattice features. Metal AM parts receive tailored blasting to remove support structure witness marks. Ultrasonic cleaning follows to eliminate residual media.

Thin-Film Coating Application

Cerakote is applied via calibrated HVLP equipment targeting 0.5-2 mils. In-process DFT measurements confirm uniform thickness across complex geometry, including lattice openings and internal passages. Polymer parts cure at 250 F, below PA12 heat deflection temperature, to prevent warping. Metal AM parts follow standard cure profiles at 250-300 F.

Three

Weight Verification and Documentation

Pre- and post-coating weight measurements quantify actual coating mass added to each part. CMM measurement confirms parts remain within the plus or minus 0.005 inch tolerance envelope. Before-and-after Ra measurements document surface finish improvement. Certificate of Conformance includes weight data, DFT readings, and dimensional verification.

Verified Weight Savings for AM Components

Weight reduction claims are verified through gravimetric analysis on every AM production lot. Pre- and post-coating measurements document the actual mass added by thin-film application, providing your engineering team with data for weight budgets and design validation.

200-400g savings per part vs powder coating

At 0.5-2 mils versus 3-5 mils, each topology-optimized component retains its designed mass advantage. For aerospace AM programs, this data feeds directly into weight and balance documentation. Surface finish improves from Ra 8-15 micrometers to under 3 micrometers simultaneously, delivering two outcomes in a single coating step.

Frequently Asked Questions

Find answers about our coating processes and technical capabilities

Can you color match Cerakote for agricultural equipment brand identity?

Yes. Agricultural OEMs use distinctive brand colors across their equipment lines, and replacement or aftermarket components need to match. We capture your brand color standard by spectrophotometer and verify every production lot to Delta E 1.5. Cerakote's abrasion resistance of 4,000 cycles per mil and chemical resistance to fertilizers, herbicides, and UV exposure means your brand color survives field conditions that destroy conventional paint within a single growing season.

Why is 40-60 PSI blasting critical for AM post-processing?

Additive manufacturing parts have inherent porosity, layer lines, and often thin-wall geometries that cannot withstand standard 80-100 PSI blasting. Our 40-60 PSI low-pressure blasting removes loose powder and partially sintered particles, reduces surface roughness peaks, and creates adequate anchor profile for Cerakote adhesion without distorting thin walls, collapsing lattice structures, or peening delicate features. This controlled approach preserves the geometric complexity that makes AM valuable.

Is passivation critical for stainless steel oil and gas components?

Passivation is essential for stainless steel oil and gas components exposed to H2S, CO2, saltwater, and other corrosive media downhole and at the surface. The ASTM A967 process removes free iron that can initiate pitting and crevice corrosion in these aggressive environments. With no dimensional change, passivation preserves the sealing surfaces and thread tolerances that pressure-rated oil and gas hardware demands.

How does chemical conversion coating protect 3D-printed aluminum parts from corrosion?

Additive-manufactured aluminum parts are especially vulnerable to corrosion due to their higher surface porosity compared to wrought stock. Chemical conversion coating per MIL-DTL-5541 creates a uniform protective layer that follows complex AM geometries without building thickness. Type I delivers 168-240+ hours of salt spray resistance (ASTM B117), and the sub-micron layer preserves the dimensional accuracy your additive process was designed to achieve.

Does ColoradoKote offer passivation for aerospace stainless steel components?

Yes. We passivate aerospace stainless steel components to ASTM A967 and AMS 2700 specifications. The acid bath process removes free iron and surface contaminants, bringing chromium to the surface to form a robust passive oxide layer. There is no dimensional change, making passivation ideal for precision aerospace stainless parts. Our facility has processed over 20,000 parts with zero quality issues, including work spec-proven for major aerospace OEMs.
