Electrolytic etching of steel knife blade

Create a mask for etching by laser

 

Over time he became Mora knife 511 my favorite working tool. Under the auspices of the fingers, I removed because I misled. Similarly, it can remove more people from my neighborhood and then we knives among them were wrong. I had somehow likely to constitute its mark. Since I use it for dirty work, I mean those that treated him a bit brutal, I had to come up with something durable. I chose the electrolytic etching depth inscription into the metal. Ordinary laser engraving could be in frequent use zošúchať. Since there are only describe the material surface.

 

 

 

Removing the guard of the knife becomes a model Mora 510th And while there may be a signed Ray Mears, so why not me?

 

 

Then top surface of the metal non-conductive coating. I used nail polish.

 

 

 

Outline a motive.

 

 

 

Where we want to remove metal etching primer. I used a method of describing the laser. Laser evaporated coating, thereby exposing the metal. Otherwise, you can sign up to scratch paint any sharp object.

 

 

 

Near you do waterproof pool to the electrolyte. Electrolyte prepared by dissolving a teaspoon of salt in a cup of water.

 

 

 

To use direct current electrolysis. So just any battery. Positive (+) pole engaging the knife and the netative (+) to the copper wire.

 

 

 

Copper wire dipping into elekrolytu reaction starts. Electrolyte changes often when it is cloudy or if already not on electrolysis. The result is always a few seconds, check that we sign nepreleptali. Otherwise, start odleptávať the edges and paint the sign of distortion.

 

 

 

Finally, nail polish remover will remove the blade. The pattern is etched to a depth of metal.

 

 

Second try

 

Later, someone still ate with my spoon. I wanted to mark it somehow, but this time I have made more of it.

 

 

Glue the surface with adhesive tape.

Although I used a diode laser, but ornaments can be carved with a scalpel. Peel off the parts we want to stick on.

 

 

 

Electrolytically etch the surface. I first applied a negative charge to the electrode, which etched the pattern a little deeper, and then applied 12V 1.2A alternating current. The surface oxidized and darkened.

The result on a smooth stainless steel looks more than good.

Ornaments are engraved slightly in depth. So they last forever.

For sure, I made some spare pieces.
