Floride Ion Cleaning (FIC)

  • Employs a chemical vapor process
  • Hydrogen fluoride gas penetrates and reduces oxides on all surfaces
  • Minute cracks will be cleaned
  • An “alloy depleted surface” is created (not detrimental to part)
  • Primarily used prior to brazing and welding repairs

Vacuum Furnace

  • 1 Heat Treat Machine
  • 1 Brazing Machine
  • Used for Age, Stress, Solutions, Aneal, Precipitation hardnesss
  • Working zone = 2’ x 4’

  • Brazing creates an extremely strong joint, usually stronger than the base metal pieces themselves, without melting or deforming the components
  • No limitation on size of part, only on the airflow
