Typical Steps in Electroplating Process

This is the process for plating steel aerospace parts with cadmium.
  • Step 1 Cleaning: surface must be free of contaminants for bonding to take place.
  • Step 2: Rinsing and dry (if needed)
  • Step 3: Acid cleaning and etching: Sand blasting with aluminum oxide will roughen up the surface so that the plating metal adheres better.
  • Step 4. Rinsing (if needed)
  • Step 5. Conversion Coating or Plating
  • Step 6: Water Rinsing (1 minute)
  • Step 7: Chemical Rinsing to make parts more rust resistant
  • Step 8: Rinse in Hot Water
