Passivation preserves the existing surface finish of polished stainless steel, including mirror finishes, brushed textures, and bead-blasted surfaces. The acid bath removes only free iron and contaminants without altering dimensions or surface texture. For automotive show pieces needing specific colors or additional protection, Cerakote can be applied over the passivated surface with color consistency within Delta E 1.5 and hundreds of finish options available.

Yes. We process DMLS stainless steel, titanium, Inconel, and aluminum AM parts with full surface preparation, passivation or chemical conversion as required, and Cerakote ceramic topcoat. Our AS9100 quality system applies the same traceability and process controls to AM parts as conventionally manufactured components. This matters for aerospace and medical AM applications where documentation rigor is non-negotiable.

Yes. Cerakote's smooth, sealed surface resists marine biological adhesion better than rough, porous raw AM surfaces. When biofouling does occur, the coating withstands the aggressive chemical cleaning agents used for marine maintenance without degradation. For AM parts deployed in submerged or splash-zone applications, the sealed Cerakote barrier prevents salt water from penetrating AM surface porosity, which would otherwise create subsurface corrosion that undermines the part from within.

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.

Yes. AM-produced fluid handling components like manifolds, fittings, and pump housings benefit from polymer coating's chemical resistance and porosity-sealing properties. The flexible coating accommodates pressure cycling and thermal expansion while maintaining a continuous barrier against process fluids. For AM parts with internal flow passages, polymer coating seals the inherent surface porosity that would otherwise allow fluid penetration into the build material, preventing both contamination of the process fluid and degradation of the AM substrate.
