What is Gold Plating?

September 28, 2010 by ·  

Gold plating is the method of electrochemically depositing a thin layer of gold onto a conductive surface. The surface being gold plated is normally a metal base which allows an electrical current to be passed through it to form a complete circuit. This allows the gold particles in the electroplating solution to bond with the item being gold plated. The item being electroplated is also referred to as the cathode.

Most plastics such as PS3 games consoles, games controllers and mobile phone casings can also be gold plated but these must be made conductive first. The gold plating of plastics is a highly specialized technique involving many processes that follow the initial first coating of silver conductive paint.

The majority of car emblems and badges are an exception to this rule. These are conductive already and simply need the chrome electro-chemically stripping to reveal the underlying nickel prior to being gold plated.

Our specially developed gold plating solutions are engineered to be extremely hard wearing and durable. This ensures that a gold plating thickness of just 5 microns is often more than adequate for the long term durability of high wear items such as jewellery and watches.

The general rule to follow is 1 year of wear per micron meaning 5 microns in gold thickness should last 5+ years if cared for properly.
