Surface Treatments
In-house, NADCAP-approved surface treatment services that enhance corrosion resistance, functional performance, and part readiness for downstream processes.
PMI offers a comprehensive suite of surface treatment services performed in-house under NADCAP-approved processes, ensuring controlled quality and traceability for critical components across aerospace, defense, medical, and industrial markets. These treatments improve corrosion resistance, surface durability, adhesion of downstream coatings, and functional performance of parts machined by PMI’s precision manufacturing operations.
Common Applications
- Corrosion resistance for machined components in aerospace, defense, and harsh environments
- Wear or friction control via dry film lubricant and PTFE coatings
- Adhesion promotion for primer/paint or secondary coatings
- Cosmetic or identification finishes for assemblies requiring consistent surface appearance
- Preparation for inspection where passivation ensures cleaner, more stable surfaces prior to verification
Technical Range
PMI’s surface treatment capabilities include a broad spectrum of chemical and coating processes applied based on part material, performance requirements, and applicable specifications:
- Passivation
- Anodizing
- Chem Film (Chemical Conversion Coating)
- Primer and Paint Systems
- Dry Film Lubricants (DFL / SFL)
- PTFE Coatings
- Non-Destructive Testing (NDT) Support — FPI / MPI
OnSite Equipment
PMI’s surface treatment operations are supported by dedicated in-house facilities and process systems designed for repeatable, controlled application, including:
- Chemical processing tanks and baths configured for passivation, anodizing, and chem film conversions
- Coating application equipment for primers, paints, dry film lubricants, and PTFE systems
- Environmental controls and staging areas to support part handling and drying/cure cycles
