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.

Application and Recycling of Tungsten Metals

Tungsten, a relatively rare and exotic metal, has been widely used in many products in our daily life.

Tungsten is not cheap because of its scarcity, but the price of tungsten is quite reasonable compared with the prices of other rare and exotic metals.

What are the Applications of Tungsten?

Tungsten is an important alloying element for the aerospace industry and the industrial gas turbine industry, because it can significantly improve the strength, hardness, and wear resistance of steel.

Tungsten filament is used in incandescent bulbs to replace tantalum, which was used many years ago, as an integral part of copper and silver electrical contacts for improved wear resistance.  Tungsten wire can also be used to manufacture direct heating cathodes and grids of electronic oscillation tubes and cathode heaters in various electronic instruments.

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.

Introduction to Aluminum, Aluminum Alloy and Aluminum Sputtering Target

Aluminum is a light metal with low density (2.79/cm3), good strength and excellent plasticity. As for aluminum alloy, the strength of super-hard aluminum alloy can reach 600Mpa, and the tensile strength of ordinary hard aluminum alloy can reach 200-450Mpa, which is much higher than steel in steel. Therefore, aluminum and aluminum alloy are widely used in machinery manufacturing.

The conductivity of aluminum is second only to silver and copper, so aluminum is used in the manufacture of various conductors. Aluminum also has a good thermal conductivity that can be used as a variety of heat dissipating materials. Besides, aluminum has good corrosion resistance and excellent plasticity, and is suitable for various pressure processing.

Aluminum alloy

Aluminum alloy can be divided into the deformed aluminum alloy and the cast aluminum alloy according to the processing method.

The deformed aluminum alloy can be further divided into a non-heat treatable reinforced aluminum alloy and a heat treatable reinforced aluminum alloy. Non-heat-treated reinforced aluminum alloy cannot improve the mechanical properties by heat treatment, and can only be strengthened by cold working deformation. It mainly includes high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum and rust-proof aluminum. The heat-treatable reinforced aluminum alloy can be improved in mechanical properties by heat treatment such as quenching and aging, and can be classified into hard aluminum, wrought aluminum, super-hard aluminum, and special aluminum alloy. The aluminum alloy can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.

Cast aluminum alloy can be divided into aluminum-silicon alloy, aluminum-copper alloy, aluminum-magnesium alloy and aluminum-zinc alloy according to chemical composition. Cast aluminum alloy is classified into four types according to the main elements other than aluminum in the composition: silicon, copper, magnesium and zinc.

Pure aluminum products

Pure aluminum products are divided into two categories: smelting and pressure processing. The former is represented by chemical composition Al, and the latter is represented by LG (aluminum, industrial). The aluminum sputtering target is a kind of pure aluminum product.

Pressure processing aluminum alloy

Aluminum alloy pressure processing products are divided into seven categories: rustproof (LF), hard (LY), forged (LD), superhard (LC), coated (LB), special (LT) and brazed (LQ). The state of the commonly used aluminum alloy material is three types of annealing (M igniter), hardening (Y), and hot rolling (R).

Aluminum sputtering target

The aluminum sputtering target is one of the sputtering targets used in the vacuum coating industry, and is therefore called aluminum sputtering target. The aluminum target is obtained after a series of processing of high-purity aluminum. It is available in a specific size and shape, which is mounted on a vacuum coater to form a film on the surface of the substrate by sputtering.
