| Any bare metal can be marked using
electrochemical etching. It is a process by which a low voltage current
passes through an electrolyte to etch away an area of a metal component.
A stencil between an electrode and the component restricts the area
of etching to the stencil design which may be a trademark, part number
or similar identification mark. |

The process takes only
one or two seconds, produces a permanent stress free mark and achieves
a clear, black oxide or white mark.
It is used extensively to mark cutlery, tools, taps, drills, saw blades
and to mark components in such as the automotive and aerospace industries.
