black oxide service process

What do we do to your parts?

For starters - we know how important your parts are and we will take good care of them and service them with great care.  Gentle handling and thoughtful packaging are a part of the process.

How do we turn them black?  The process is fairly gentle and adds virtually zero thickness to your part.  In a nutshell, all we are doing is cleaning them off, rinsing the soap off, dunking them in a heated salt bath that converts the iron into a naturally occurring black iron oxide, then rinsing and adding a final supplementary finish.

See that's not so bad, right?

The (5) basic steps to our service includes:

  1. Clean
  2. Rinse
  3. Black Oxide
  4. Rinse
  5. Rust Preventative (supplementary finish)

Within each of the process steps listed above a disciplined set of controls exist around times, temperatures, concentrations and other important factors that we monitor to ensure that your parts have the same great finish every single time.

Our service and process was designed by our owner who has over 20 years of experience designing highly technical and capable processes for the Aerospace and Automotive industries.  His most recent claim to fame was receiving a patent for a manufacturing process to fabricate a component for the GE GEnx turbofan for airplanes!
