Electrochemical Coatings

Gold and Platinum Plated

Electrochemical coatings are a type of process used to impart protective, decorative or functional properties to metal surfaces. This coating method takes place in a coating bath using electric current.

One of the most important issues to be considered in metal fabrication projects is the requirements of the part to be manufactured. The manufacturing method is selected according to the shape, material and other requirements of the part. Production time and efficiency should also be taken into account in parts that will be mass produced. 

In automotive, aviation, furniture, kitchen, architecture, interior architecture and many other sectors, in short, products are produced with additive, machining and welded manufacturing for parts wherever metal and alloy are used. 

It is usually made for decorative purposes, to increase corrosion resistance, improve electrical conductivity, or to impart special properties in certain industrial applications.

Advantages of Gold Plated:

  1. Corrosion Resistance: Gold is highly resistant to oxidation and corrosion, so coated objects will last a long time.

  2. Electrical Conductivity: Gold is an excellent conductor of electricity, so it is used in electronic components.

  3. Aesthetic: Gold plating gives objects a luxurious and attractive appearance.

  4. Chemical Inertness: Gold is inert to many chemicals, making it ideal for medical applications.

Usage areas:

  • Jewelery and Watchmaking: Because gold is an expensive material, sometimes jewelery and watches are produced with gold plating to be more economical.

  • Electronic Components: Gold plating is used on ports, circuit boards and other components because it provides excellent electrical conductivity and does not oxidize.

  • Medical Devices:Due to the chemical inertness of gold, it is used as a coating in some medical devices.

  • Decorative Items:Plaques, awards, ornaments and other luxury items are plated with gold as a decorative touch.

  • Headphones and Other Fasteners:Gold plating is frequently used in audio equipment due to its resistance to oxidation.

​Gold plating is used to add aesthetic, protective or functional properties to the surface of an object.


Platinum Plated

Platinum is used for industrial and decorative purposes as it is a chemically inert substance resistant to corrosion and wear.

Advantages of Platinum Coating:

  1. Corrosion Resistance: Platinum is highly resistant to oxidation and corrosion.

  2. High Temperature Resistance:Platinum is resistant to high temperatures and this property is useful in industrial applications.

  3. Chemical Inertness: Platinum is inert to many chemicals, making it ideal for some medical and industrial applications.

  4. Aesthetic:Platinum plating gives objects a sophisticated and high-quality look.

Usage areas:

  • Jewelry: Platinum is known for its bright white color and is used in jewelry as an alternative to gold.

  • Electronic Components:The excellent conductivity and corrosion resistance of the platinum coating makes it popular for use in ports and sensors.

  • Catalysts: Platinum is used as a catalyst in automotive exhaust systems and in the petrochemical industry.

  • Medical Devices:Because of its chemical inertness, platinum is used as a coating in some medical devices.

Platinum plating is a high quality plating option with both aesthetic and functional advantages. However, the high cost of platinum can make plating processes generally only economical for specific and high value applications.
