1 What is gold plating? Gold plating is a process where a thin layer of gold is bonded onto a base metal. Plating is quite common in the jewelry world, with gold and rhodium being two popular types. This process was invented by an Italian chemist, Luigi Brugnatelli in 1805, the first person to plate a thin coat of gold onto silver.
Solutions used in plating bright, hard gold from an acid medium are described in Table VI. Hard, Bright Gold on PrintedCircuit Tabs Plating of printedcircuit edge connectors is a major segment of the goldplating industry. The solutions used are also the acid hard, bright golds.
(Different Types of Gold Plating Solution)
#0183;#32;Gold plating services are offered in a variety of types. For instance: soft, pure gold plating, and bright, hard gold plating. Soft, pure gold plating, deposited from special electrolytes, can be used for wire bonding and circuit boards.
Gold plating is the practice of making changes to a project that are outside of the original agreedupon scope .

Another type of plating is rolled gold plating, which is thicker than electroplating. This plating process relies on heat and pressure for bonding. Gold Filled This is a rather deceptive name since the jewelry is not actually filled with gold in the way that you would picture something like a filled doughnut.
Adding gold plating or silver plating to an item to make it appear more precious and attractive is an extremely common use for plating. However, there are many other uses including corrosion inhibition, radiation shielding, paint adhesion and many more. There are also a few useful different types of plating methods.
Gold plating Wikipedia
Gold Electroplating is a method of depositing a thin layer of gold onto the surface of another metal. Gold plating finds its uses in jewelry, semiconductor industry. It often employed in electronics to provide a corrosion resistant surface. In this instructable, I am making alkaline gold plating solution which can deposit gold by electrolysis.
#0183;#32;Nitridebased gold compounds are another form of gold plating solution. Considered better for electronics applications because of reduced cost and better durability, gold nitride solutions replace the need for bonding gold to toxic elements,
#0183;#32;However, gold plating, like most types of metal finishing, can be done in a number of other ways. The gold metal can be suspended in a solution, which is then brushed on the object being plated. The goal is to maximize the effect but to minimize the amount of gold needed to do the job.

Gold jewelry is actually an alloy or mixture of gold and other types of metals. The composition of the alloy determines the color of the gold. Different shades of gold jewelry have become very popular in recent years. In fact, while yellow gold used to reign supreme as the preferred color for wedding rings, white gold is now a more popular choice.
Barrel plating is a method we may use for plating gold, silver, palladium, rhodium, tin, copper or nickel for small parts in large groups without using the rack method. This method is particularly effective when plating small, durable parts like fasteners, as it is much less costly than the rack method.
There are different metals used as the base metal in costume jewelry. Some of these base metals would contaminate gold plating tanks. It is for this reason that a different metal is plated in a prior step to the gold plating. Gold plating has varying levels of clingyness to different metals. For example gold has an affinity to silver.
Many types of metals, especially gold, Creating compatibility between different metals The next step is to place the drum in a plating solution consisting of dissolved gold ions and chemical additives and rotate it slowly to apply the coating.
Potassium gold cyanide is the most important gold plating chemical. Almost all the gold used for contacts in the electronic industry is derived from potassium gold cyanide. The older route to KAu (CN)2 started with the dissolution of metallic gold in aqua regia.
