Passivation

Passivation

Passivating steel removes all impurities from the part or component and creates a hard non-reactive surface film that inhibits further corrosion.

Passivation Capabilities

Type of Process
Passivation treatments for cleaning and descaling corrosion-resistant parts, components, equipment and systems.
Features
Passivating steel removes all impurities and creates a hard non-reactive surface film that inhibits further corrosion.
Process Approvals
For Passivation we adhere to:
  • AMS 2700: Passivation of Corrosion Resistant Steels
  • BAC 5625: Passivation of Corrosion Resistant Steels (Type II)
  • BAC 5751: Passivation of Stainless Steel
  • DPS 9.07: Surface Treatment of Corrosion Resistant Steels
  • GAMPS 4103: Acid Cleaning of Ferrous Alloys
  • GSS 7021: Acid Cleaning of Ferrous Alloys
  • AMS-QQ-P-35-98: Passivation Treatments for Corrosion-Resistant Steel
Material
Acid cleaning creates passivating layer a few atoms thick.
Base Materials Worked
Steel, Stainless Steel
Types
Passivation treatments shall be of the following types:
  • Type II - Medium temperature nitric acid solution with sodium dichromate additive
  • Type VI - Low temperature nitric acid solution
  • Type VII - Medium temperature nitric acid solution
  • Type VIII - Medium temperature high concentration nitric acid solution
Automation
All Passivation processes are performed manually to ensure the proper care is given to each step.
