One of the most commonly used methods to create such a tip is electrochemical etching of a metal wire. The process of electrochemical etching involves applying a potential difference between a cathode ...

and with accuracy better than the industry standard for aluminium etching. Using photo-resist and etchants to chemically machine selected areas accurately, the etching process is characterised by ...

While most of the time the name of the game is to remove a lot of metal, etching is an entirely other process. If you just want to put a logo on a piece of steel, or etch some labels in a piece of ...

Vinyl masks were first applied to polished aluminum substrates, followed by a two-step etching process that created micro- and nanotextured zones. The team then used advanced imaging techniques to ...
