How to make a simple electroplating machine for nickel plating at home

Nickel, with its high corrosion resistance, perfectly protects other metals from corrosion and gives them an attractive appearance. It is not difficult to assemble a galvanic installation for nickel plating in a home workshop and does not require expensive materials.

It will take

Materials and fixtures:

  • two nickel anodes;
  • bowl-shaped container;
  • wires;
  • Crocodile clips;
  • 4.5V battery;
  • power supply;
  • plug for connecting wires to a power source;
  • salt;
  • ten percent vinegar;
  • old lighter body.

Nickel Plating Plant Manufacturing Process

Since galvanic processes are not harmful to humans, we take all available safety measures, including ventilation of the room and the presence of protective gloves.

Pour vinegar into the container and lower the two nickel anodes. We connect the wires to them, and the second ends to the terminals of the 4.5 V battery.

After a while, bubbles will begin to evolve on the negative plate and the electrolyte will be enriched with nickel ions.

We insert and fix the pieces of wire in the adapter, to which we connect the wires.

We set the voltage to 5 V on the power supply unit and plug it into the network. We connect an adapter to it, but we don’t see anything special.

After adding salt to the vinegar, its conductivity increases, and the multimeter records an increase in current.

Now you can clearly see bubbles of hydrogen released on the negative plate, and oxygen – on the positive one.

After two hours, the formation of nickel ions increases even more, which is confirmed by the reading of the multimeter.

At the same time, vinegar, partially turning into gas, is released from the electrolyte, which is immediately felt by the sense of smell. Therefore, we quickly ventilate the room.

Our setup is up and running, and we are replacing the negative plate with a part that we are going to nickel. We see that a lot of nickel has settled on the plate, probably due to the fact that the plates were too close to each other for a long time. To optimize the nickel plating process, we use a coin carefully polished and degreased with acetone. Since we have replaced the negative plate with it, nickel ions “Ni2 +” will be deposited on it from the electrolyte.

Positively charged nickel ions are electrically converted to metallic nickel and deposited on the surface of the coin in a thin and durable layer.

After 15 seconds, a beautiful thin coating appears on the coin. To strengthen it, we intensively move the coin through the clamp in all directions. After two minutes of electroplating nickel plating, the coin is unrecognizable.

The electrolyte heats up during nickel plating and this is recorded by a temperature meter – 29.3 degrees Celsius. At the same time, the walls are colder – 18.3 degrees Celsius, as well as a container with water – 18.1 degrees Celsius. The electrolyte temperature clearly influences the nickel plating process. So, if it is equal to 19.2 degrees Celsius, then nothing happens to the coin in 10 or even 30 seconds. But with an increase in the electrolyte temperature to 40 degrees Celsius, due to the additional connection of a 4.5 V battery, the quality of nickel plating increases markedly.

Before nickel plating, we remove oxidized places from the body of an old lighter on an emery wheel, since they do not conduct current and therefore do not nickel. Also, the coating will not be smooth and shiny.

Next, remove the grease and fat from the parts with acetone. They also do not conduct current and therefore the quality of the nickel plating will be low.

Lighter parts are larger than coins, so we keep them in electrolyte longer.

The quality of nickel plating will be higher if the parts are constantly moved in the electrolyte and turned over. Nickel plated lighter body outperforms an uncoated lighter.
