Passivation – a chemical process that can increase the corrosion resistance of metal – has applications in numerous industries and products.  EMI’s passivation services, which adhere to a range of industry standards, can provide you with the level of durability you need in even the most corrosive environments. 

Passivating Machined Parts

The machine tool industry has made significant use of passivation of machined parts.  Passivation can add to the outer protective layer naturally produced by many metal alloys on a nanometer scale, giving machined parts increased corrosion resistance while allowing the finished part to stay within tolerance.  Passivation is suitable for a range of machined components, including:

  • Drawings
  • Rods
  • Fittings
  • Tanks
  • Discs
  • Stampings
  • Weldments
  • Castings
  • Spinnings
  • Forgings
  • Fasteners (screws, bolts and washers)
  • Pipes and tubing
  • Valve stems and bodies



Passivation for Food, Beverage, & Dairy Processing Equipment

The manufacturing and processing environments found in the food and dairy processing industry frequently involve temperatures and substances that can do a lot to foster corrosion in steel components.  EMI provides first-class passivation services for the food, beverage and dairy processing industries.  We have experience with passivation of a range of components, including:

  • Filters
  • Screens
  • Tubing
  • Dryers
  • Mixers
  • Piping
  • Product Trays
  • Storage tanks
  • Product impellers
  • Fermentation vessels
  • Dry product delivery systems


Passivation for Cleanroom Manufacturing Facilities

Cleanroom facilities, particularly in the semiconductor industry, require non-contaminating surfaces in all areas, even in situations where caustic chemicals and solutions are used in manufacturing processes. To prevent metals used in cleanroom settings from corroding over time, passivation is frequently employed. We have provided quality passivation services for a range of products and components used in cleanroom manufacturing facilities, including:

  • Equipment consoles
  • Light fixtures
  • Vacuum chambers
  • Manufacturing & processing equipment
  • Gas & fluid distribution systems
  • Exposed electrical conduit & outlet boxes
  • Tables, chairs, & waste containers


Passivation for Medical Devices

Medical devices can’t afford to have corrosion contaminate delicate electronics and components. EMI has provided passivation services for a range of medical devices and equipment, including:

  • Surgical instruments, including:
    •      Scalpels
    •      Staplers
    •      Biopsy Instruments
  • Battery components
  • Orthopedic implants
  • Bone screws
  • Pacemakers & defibrillator electronic circuit boards
  • Robotic instruments
