网页Gold plating isn't like spray painting or something as superficial as that. It's actually a chemical process. When an electric current applies a thin layer of gold to another metal, it partially dissolves that metal; this is when the chemical bond is created. That means that the gold fuses with the other metal, meaning it is attached really well.
