Electrochemical Etching is used for direct part
marking of electrical conductive material surfaces, what we need for etching
is a controller and some consumable material like Electrolyte, felt and
stencils. During the etching process the basic material surface is rapidly
forced to oxidation and that makes it possible to penetrate the material
surface. The meaning oxidation originates from chemistry and means that an
agent is combining with hydrogen i.e. a chemical reaction is released and
hydrogen is delivered Electrolytes are preparations made by different salts.
Another description is the Electrolytic marking process is based on material
remove (erosion)or on an oxidation attack to the basic material.
Most economic and reasonable
direct part marking system.
No deformation stress, material
cracking, structure alterations or thermal impairments on work piece
surfaces are known.
The marking is completely
edgeless (applied on precision gauges also).
The marking itself is permanent,
sea-water resistant, acid-resistant and resistant on abrasion.
The pH value of an Electrolyte has a major
influence on the quality and on the sensitivity with regard to the corrosion
is much higher. The oxidisation (rust) can only be stopped by applying the
neutrality carefully after the marking. Especially for marking on steels
with a high content of carbon, we recommended to only use electrolytes with
a neutral ph
