how does metal plating work?


im pretty big into knives and a lot of the time ill see silver plated metals but i have no clue how it actually works (like chemically i know how to do it)

In: Chemistry

Electrolysis is the name of the chemical reaction. It happens when you put a + and – node inside a solution. Lets say you want to plate silver Ag; well you would need Ag+, so you would need to create a solution that would dissolve the metal Ag into Ag+.

When the electrical current is started the Ag+ will migrate to the negative node and cover it up. So your neg node will be what you want plated.

Of course it’s a lot more complicated than that but thats kinda the gist of it.
