Electroplating: using the principle of electrolytic on some metal surface on a thin layer of other metal or alloy plating process.
Mainly to prevent metal oxide (
Such as rust)
And improve the wear resistance and electric conductivity, reflective resistance, corrosion resistance,
Copper sulfate, etc. )
Beautiful and improve, and so on.
A lot of outer layer for electroplating of the coin.
1, copper plating: with render, improve plating adhesion ability, and ability to resist corrosion.
2, nickel plating: render made the appearance, or improve the corrosion resistance and abrasion resistance.
3, gold-plated: improve conductive contact impedance, improve signal transmission.
4, palladium plating nickel: improve conductive contact impedance, improve signal transmission, wear resistance is higher than gold.
5, tin lead: improve welding ability, quickly replaced by the other for objects.
6, silver plated: improve conductive contact impedance, improve signal transmission.
