how to clean deposition materials shipped in oil
In order to protect some deposited materials from reacting with air or water vapor, they are usually immersed in low-viscosity (hydrocarbon) mineral oil during storage and shipment. Before installing these composition materials shipped in oil into the vacuum system, we must use solvents to remove these oils. The choice of solvents is based on the premise...

Does Titanium Never Corrode_
Titanium can be alloyed with iron, aluminum, vanadium, and molybdenum to produce strong, lightweight alloys for aerospace (jet engines, missiles, and spacecraft), military, industrial processes (chemicals and petrochemicals, desalination plants, pulp, and paper), automotive, marine, human implants, and other applications. In addition to low density and high specific strength, another important advantage of titanium alloy...

electron beam evaporation
Electron Beam Evaporation – Definition Electron beam evaporation, or E-beam evaporation, is a type of physical vapor deposition (PVD) technique, which directly heats the evaporation material (usually pellets) by using an electron beam under vacuum, and transports the vaporized material to the substrate to form a film. Electron Beam Evaporation – Working Processes Electron beam evaporation...

Platinum vs. Gold Ring
As for the two most commonly used metals for engagement and wedding rings, platinum and gold, most people distinguish them by their different colors-platinum is naturally white, and gold is naturally yellow. However, rings made of white gold (composed of gold, alloys, and a rhodium plating) have a similar white color to platinum rings. Since...

Semiconductor wafers are the basic material for manufacturing electronic chips. The most important raw material for semiconductor integrated circuits is silicon, which is widely found in rocks and gravels in the form of silicates or silica in nature. The fabrication process of the semiconductor silicon wafer can be divided into three basic steps: silicon purification...

Sputtering targets are a physical vapor deposition (PVD) mechanism with many uses in modern technology and manufacturing. In the sputtering process, the atoms are pulled from the sputter target with powerful magnets, and a controlled gas (usually argon) is introduced. Then, the processed to collide with each other in their gaseous state before condensing into...
