How to Dip Chrome

Chrome dipping is also referred to as chrome plating and is used to add decorative luster to a hard or soft metal. The chrome dipping process requires a bucket full of premixed electrolyte, a cathode and an anode. The cathode is the piece of metal you wish to chrome. The anode is a flat piece of nickel. Both the cathode and anode are dipped into the electrolyte before a car battery is used to create a charge -- sending nickel particles from the anode onto the cathode to create a chrome finish.

Things You'll Need

  • Work gloves
  • Dust mask

  • Nickel plate (1/8-inch thick by four-inches long)
  • 33 oz. chromic acid crystals
  • 0.33 oz. sulphuric acid fluid
  • 3.79 liters of distilled water
  • 12-volt car battery
  • Copper wire
  • Copper pipe
  • Bucket

Instructions

    • 1

      Add the distilled water to the bucket. Carefully add the chromic acid crystals and sulfuric acid fluid. Always add ingredients in this order.

    • 2

      Lay a copper pipe across the top of the bucket.

    • 3

      Attach a copper wire to the positive battery connection. Tie the nickel plate -- the anode -- to this other end of the copper wire. Dip the anode into the bucket.

    • 4

      Attach a second copper wire to the copper bar. Tie the copper plate -- the cathode -- to the other end of the second copper wire. Dip the cathode into the bucket.

    • 5

      Allow the chroming process to commence for 75 minutes. The electrolyte mixture will begin to turn brown as the chroming commences -- an indication of microscopic pieces of nickel that are being removed from the anode and adhering to the copper plate -- the cathode.
