I have considerable reservations about using electrolysis, at least in the crude way that a lot of YouTubers seem to go about it.
No accurate, if any, control of voltage or current; which can lead to unwanted effects, like hydrogen embrittlement of some types of steels.
And no grasp of the concept of 'current density' i.e. the total current divided by the surface area of the workpiece, to yield a figure in A/m^2.
Any electroplater will tell you that these are the critical control parameters, for this sort of work.
