Special Processes

There are many special, stand-alone¬†processes that provide distinct characteristics desired from a particular material. There are also supplemental treatments that provide cosmetic, engineering, or a combination of both to improve and finish the part.¬† All of ElectroLab‘s Special Processes are NADCAP accredited, with the exception of zinc phosphating.

Sometimes these processes are part of the requirement of a particular government, military, AMS, ASTM, or customer engineering specification, while others are covered by their own unique specification.

Special processes that are provided by ElectroLab that are considered stand-alone processes and have their own specifications are:

  • Electroless Nickel
  • Passivation
  • Chemical Film
  • Zinc Phosphate
  • Cleaning & Pickling
  • Black Oxide (Copper Alloys)
  • Black Oxide (Steel)
  • Black Oxide (SS)
  • Electropolish Stainless Steel
  • Electropolish Aluminum

Supplemental Special Processes

Special processes that are supplemental and usually part of a government, military, AMS, ASTM, or customer specification include:

  • Chromate Conversion Coatings for Zinc & Cadmium in Yellow, Clear, Black, & Olive Drab
  • Thermal Treatment for Stress Relief Prior to Plating
  • Hydrogen Embrittlement Relief After Plating for Parts That Have Been Hardened
  • Application of Supplemental Corrosion Inhibiting Oil-Based or Nitrite-Based Corrosion Inhibitors to Prevent Corrosion upon Storage
