There are several methods for putting a gold coating on an industrial object. For years, metal finishing companies and manufacturers have favoured electroplating, yet a newer technology known as PVD coating is quickly gaining traction in many production circles. We’ll look at the distinctions between the two to see why gold plating is preferable for your manufacturing processes.


The electroplating method uses electrodeposition to apply gold or other metals to the surface of a substrate. The procedure requires immersing the workpiece in an electrolyte solution in a tank. The dissolved ions of the chosen metal — gold in this case — are present in this solution. As a result, the method is also referred to as ion plating. DC energy is introduced into the plating bath, which attracts positive ions and drags them to the workpiece, where electrodeposition occurs.


Physical Vapor Deposition (PVD) is an acronym for Physical Vapor Deposition. PVD Coating is a term used to describe several thin film deposition processes. The solid material is vaporised in a vacuum and deposited on substrates as a pure material or alloy composition coating. Because the coating material is transferred as a single atom or on a molecular level, the procedure can produce exceptionally advanced and high-performance coatings, which can be preferable to conventional methods in many situations.

PVD Coatings are at the heart of every microprocessor and semiconductor device, as well as every durable protective film, optical lens, solar panel, and many medical equipments. PVD gives the solution whether the coating needs to be ultra-thin, pure, durable, or clean. As a result, it is used in a wide range of industries, including optical applications such as eyeglasses and self-cleaning tinted windows, photovoltaic applications for solar energy; device applications such as computer chips, displays, and communications; and functional or decorative finishes such as durable hard protective films and brilliant gold, platinum, or chrome plating.

Sputtering and Thermal Evaporation are the two most popular Physical Vapor Deposition Coating techniques. Sputtering is the process of bombarding a coating substance called the target with a high-energy electrical charge, causing it to “sputter” off atoms or molecules placed on a substrate such as a silicon wafer or solar panel. In thermal evaporation, a coating material is heated to its boiling point in a high vacuum atmosphere, producing a vapour stream to rise in the vacuum chamber and condense on the substrate.

Increased durability and enhanced coating adhesion are two of the benefits of PVD coating. However, the quality of the method and the provider’s ability can have a significant impact on the outcome. Many businesses still appreciate the advantages of traditional gold plating, which include: Gold plating has been a tried-and-true metal finishing procedure for decades, delivering consistent long-term results. On the other hand, PVD coating in mass production is still a relatively new method with limited experience.

Coating uniformity: Electroplating can reach regions where other PVD methods can’t. As a result, gold plating often results in a more even and uniform surface layer.

Variable thickness: Gold plating gives you more options when it comes to attaining the perfect coating thickness. To fulfil the manufacturer’s exact requirements, this process can produce coatings ranging from very thin to exceedingly thick.

Increased masking potential: Some manufacturers may prefer to plate some but not all sections of a workpiece. Compared to PVD coating, gold plating is more suitable with these selective plating applications.

Reduced energy consumption: Electrodeposition of gold requires a low-voltage electrical current. On the other hand, physical vapour deposition frequently happens at temperatures of 900 degrees Fahrenheit or more significant. Therefore, when employing PVD, the increased energy usage can raise the project’s cost.

Smart Microns Gold Plating Service

 The gold plating on jewellery offers an item the beautiful appearance of gold without being totally made of gold. Because gold is so expensive, many people will not buy a solid gold piece of jewellery. The beauty of gold plating is that it allows you to give a piece all of the qualities of gold without the expensive cost. Even though gold was usually reserved for the wealthy, it has enthralled people throughout history, from Ancient Egypt to Mesoamerican societies.

In 1805, an Italian chemist named Luigi Brugnatelli invented the modern gold plating procedure. Since then, everyone can join the golden aesthetic with more affordable alternatives to authentic gold jewellery. If you’re seeking for gold plating services in Chennai, Smart Microns is here to help.
