Electrochemical or electrolytical marking

The electrochemical marking (sometimes called “electrolytical marking“) provides a permanent marking without “stress” on the most conductive metals even on the hardest ones (such as carbide)

Principle

This process is used to mark conductive metals even the hardest ones (such as carbide). according to the following principle:

A chemical reaction is created between an electrolyte and the metal, this reaction occurs only if there is a passage of electric current (low voltage).

 

This current can be:

  • Either alternative: the reaction converts the metal into oxyde, the obtained marking is black in appearance for the gray iron and copper metals or white / gray for the aluminum alloys.
  • Either continuous: there are material removal and engraving (colorless)

The text or the drawing to mark is defined by a “stencil” which allows the electric current and the electrolyte to pass on the parts to be marked.

The configuration for electrochemical marking is therefore always :

  • A low voltage AC / DC generator
  • A conductive current marking head (electrode) that will bring the current from the generator to the part to be marked, and also to the electrolyte
  • size of the area to be marked, the size of the series, the repeatability of markings, the automation degree, etc.

 

Applications

Materials Applications fields
  • Iron metals
  • Stainless steel
  • Aluminium
  • Inconel
  • Titanium
  • Fragile parts of the aviation and nuclear industry
  • Tooling
  • Cutlery
  • Medical devices
  • Identification plates marking
  • Data-Matrix code marking
  • Deformation grids marking (deformation stress measurement on mechanical parts)

Advantages

  • Unalterable, does not deform the material, does not create “stress”, does not weaken or reject the material
  • Economic: relatively small investment for long life lasting
  • Flexible: whether the parts are round, flat, concave, convex
  • Aesthetics : texts, logos even complex graphics, barcodes, 2D (Data Matrix) codes
  • Flexible: the simple use of a printer, connected or not to a computer, allows very fast and on demand execution of marking masks (stencil)
  • Fast: marking in 1 to 3 seconds
  • Safe: the used electrolytes are little or not dangerous at all in most cases
