ELI5: does steel heated with an electric current oxidise in a similar way to steel heated in a conventional forge?
When watching forging videos on YouTube, you can see that metal heated oxidises, and the resulting scale comes off when the steel is struck with a hammer. Would the same thing happen if you were to hook that same piece of steel up to, for example, a powerful battery and run an electric current through it to heat it up? And why/why not?
