Types of Silver Plating Equipment
Platinum plating refers to the application of a thin layer of platinum onto a surface or object, which is typically made of a different metal. This process is accomplished through various commonly used methods, which are also used for silver plating. It's worth noting that platinum is more expensive than gold, making platinum plating less common compared to gold or silver plating. The demand for platinum plating has been steadily increasing due to its remarkable resistance to wear and tarnish, which surpasses that of both gold and silver.
- Electroplating: This is the most common method of platinum plating. It uses an electric current to deposit a layer of platinum onto a surface after immersing the object in a solution containing platinum salts.
- Electroless Plating: This is a chemical plating process that deposits platinum onto a surface through a chemical reaction without the need for an electric current.
- Platinum Sputter Coating: This is a physical vapor deposition (PVD) method in which platinum is deposited onto a surface by sputtering platinum particles from a target onto the object's surface.
- Laser Platinum Bonding: This is a technique that uses a laser to heat a platinum layer and bond it to the surface of another material. This method is used in specialized applications where a strong, localized bond is required.
- Alloying and Diffusion Bonding: These are methods in which platinum is combined with other metals to form an alloy, which is then used to coat a surface. Platinum can also be bonded to another metal through diffusion, where the platinum and metal are heated together until they intermixed at the atomic level.
Each of these methods has advantages and disadvantages, depending on the application's specific requirements. Also, some methods are more suitable for certain types of objects or substrates.
