3 Minutes to Know PVD Gold Sputtering

Gold is a popular precious metal that has been used for centuries as currency, hedging and jewelry for its noble and beautiful gold color.

PVD Gold Sputtering

Gold sputtering coating is a thin film deposition process in which gold or gold alloy is bombarded with high-energy ions in a vacuum chamber, causing gold atoms or molecules to be “sputtered” into the vapor and condensed on the substrate to be coated. Sputtering is one method of the PVD (Physical Vapor Deposition) process, the other two of which are thermal evaporation deposition and electron beam vapor deposition, and gold is also applied in these two methods. In thermal evaporation deposition, gold evaporates in a low-pressure environment with resistive heating elements; and in electron beam vapor deposition, gold is heated by an electron beam, and then condensed on the substrate to be coated.

Gold Plating

Apart from PVD coating, there are other ways for gold coatings such as gold plating and gold filling. Gold plating is a method that deposits a thin layer of gold on the surface of another metal by chemical or electrochemical plating. The advantages of gold plating are inexpensive and easy. However, the coating it produces is relatively soft and less durable, and what’s worse, its chemical process would cause pollution that is far away from environmentally friendly.

Gold Filling

Gold filling is the mechanical bonding of gold to metal under high temperatures and pressure. It produces a thicker coating than PVD gold sputtering and gold plating, and thus it is usually more expensive.

Advantages of PVD gold sputtering

The constant contact of skin or clothing may abrade the coatings, especially in the watch and jewelry industry. Thus, PVD gold sputtering is preferred in these two industries because the coatings it produces are harder and more durable than that of electrolytic gold plating or gold filling.

Compared to other types of gold coatings, the main advantages of PVD gold sputtering coating are their durability, retention of gloss, corrosion resistance, and abrasion resistance in contact with the skin, thus extending the life of the jewelry. PVD gold sputtering not only provides the exact color and brightness which evokes the general feeling of love and attraction with jewelry, but also has the advantage of being more environmentally friendly and durable than gold plating or gold filling for producing a gold coating.

Stanford Advanced Materials(SAM) is a global sputtering targets manufacturer which supplies high-quality and consistent products to meet our customers’ R&D and production needs.

Tungsten sputtering target & Ta evaporation pellets can be used as wear-resistant coatings for mechanical parts, as evaporating filaments for physical vapor deposition (PVD) of aluminum and silver, and as key barrier electrons for barrier coatings in critical electronic devices.

Some of the other applications of Tungsten include the component of chemicals and catalysts, cutting blades, paints, pigments, inks, lubricants, etc.

How to Recycle Tungsten?

Tungsten’s unique properties of heavy weight, high hardness, and high melting point make tungsten waste ideal for recycling. The fact that it is chemically resistant is a key factor in tungsten recycling. Therefore, recycling tungsten-bearing scrap is more popular. The methods of tungsten recycling can be roughly divided into the direct method and the indirect method.

Direct Tungsten Recycling

The direct method means that the tungsten waste is converted into a powder of the same composition by chemical or physical treatment or a combination of both. A typical example of a direct method is a zinc treatment method. This method has many advantages, such as limited energy consumption and chemical waste, as well as low production costs. A disadvantage of this method is the limitation on recycled materials.

Indirect Tungsten Recycling

Indirect methods, such as wet chemical processing, are commonly used in refining processes. This type of recycling has no restrictions on materials, but requires a lot of chemicals and energy.
