PTFE impregnated surface treatment.
Hard coat anodize impregnated with PTFE for a dry-lubricated, low-friction surface on sliding and wear parts.
The 30 second version
What does PTFE impregnation do?
A hard anodic coating is porous at the microscopic level. Impregnating those pores with PTFE puts a dry lubricant inside the wear surface itself, so the part carries its own low-friction layer without grease or coatings that rub off. The result is a hard coat that slides: valves, pistons, guides, packaging machinery components, and any aluminum part that moves against another surface.
Where it earns its keep
Sliding parts that cannot be greased.
Food and packaging equipment, medical assemblies, and automation components often cannot tolerate wet lubricants. PTFE impregnated hard coat gives them a clean, dry, self-lubricating wear surface that lasts.
DARK FINISH WORK · THE BENCHThe spec side
AMS 2482 and the print.
PTFE impregnated hard coat work is commonly specified under AMS 2482, and engineers searching that spec are usually searching for exactly this process. The base coating runs like our standard Type III hard coat, with the impregnation step added. SAE publishes the AMS specifications at sae.org/standards.
How it runs in Paoli
PTFE impregnation, step by step.
Confirm the spec intent
AMS 2482 or a performance need in plain words. We confirm the coating build and the impregnation approach on the quote.
Hard coat first
The part gets a Type III hard anodic coating, grown porous and dense.
Impregnate the pores
PTFE goes into the coating pore structure, becoming part of the wear surface rather than a layer on top.
Function check and return
Finish verified against the callout, packed, and back on the standard clock.
Questions
Common questions on this service
Is PTFE impregnation the same as a Teflon coating?
No. A sprayed coating sits on top of the part and can wear off. Impregnation puts PTFE inside the pores of the hard anodic layer, so the lubricant is part of the wear surface itself.
What color does it come out?
PTFE impregnated hard coat typically runs in the dark gray to black range, consistent across the batch.
Can you run it on existing hard coat?
It is applied as part of the coating process, so plan for us to run the hard coat and the impregnation together. Send the print and we will confirm.
How long does the dry lubrication last?
As long as the coating itself, because the PTFE lives inside the oxide pores. It wears only as the hard coat wears; it cannot flake off the way a sprayed film can.
Is it suitable near food or cleanrooms?
PTFE impregnated hard coat is a dry, clean surface used on packaging and food-machinery components. Put the compliance requirement on the RFQ and we will confirm fit.
