Electro-chemical engraving on a knife
Electro-chemical engraving very simple. It will not require you to know any peaks in the field of chemistry or physics. Anyone can make it, and the necessary ingredients are available in every home. With this engraving method, you can apply a design not only to a knife, but also to any other metal surface.
We will apply the design to the knife:
This Chinese character means meat!
What do we need? - Firstly, the knife itself, I took a kitchen cleaver:
The engraved surface must be cleaned and degreased! The quality of the applied pattern depends on this. You can degrease it with gasoline, alcohol, cologne, etc.
Next step: You need to stick the tape and cut out our hieroglyph on it. You need to cut it with a very sharp scalpel or a stationery knife.
Do everything carefully so that the tape does not come off where it is not needed.
Next we will need:
Power supply for 5....12 volts, telephone charging is also suitable;
A cotton swab or a piece of cotton wool wrapped around a nail;
And the solution: a teaspoon of salt dissolved in 50 grams of water.
Everything is prepared, we begin electrochemical cleaning of the metal surface.To do this, you need to attach “+” to the cleaver, and “-” to the nail on which the head of the cotton swab is placed - this will be our electrode.
We turn on the power supply, dip the electrode in a solution with salt and draw it across the surface of our drawing. For better quality, you need to go through it 2-3 times slowly. But don't succeed.
Everything has been cleared. Next, replace the cotton wool or the head of the cotton swab with a clean one. Change the polarity of the power supply: plus to the electrode, minus to the cleaver.
We wet the electrode in the same salty solution and begin to draw a picture:
The drawing appears before your eyes. The outline immediately begins to turn black. We also do it 2-3 times for better effect.
That's it - the engraving is ready. Peel off the tape and wash off its sticky traces.
Well, it’s up to you to decide which drawing you choose! Good luck.
