Hola, Matchlock

No existe óxido estable: la película de óxido sigue carcomiendo debajo de su superficie, aunque en apariencia permanece inmóvil. Hasta en el pavonado (en realidad una oxidacion controlada) si no se sigue un tratamiento adecuado, termina en una oxidacion severa.
La electrólisis es inocua para el metal, y se basa en la propiedad del hidrógeno naciente para descomponer el óxido. Lo mismo pasa con el método de zinc-soda.

Saludos, Fernando

Hello, Matchlock

There is no stable oxide, the oxide film is eating away beneath its surface, although seemingly immobile. Even the peacock (actually a controlled oxidation) not following proper treatment, ending in a severe oxidation.
Electrolysis is safe for metal, and is based on the ownership of the nascent hydrogen to break down rust. Same with the zinc-soda method.

Regards, Fernando
