You must have heard about aluminium or seen aluminium in many different places. This is because aluminium is one of the most useful elements that nature offers. In terms of occurrence, studies show that aluminum comprises about 8% of the earth’s crust, making it the most abundant metal and the third most abundant element in...Continue Reading
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...Continue Reading
Magnetron sputtering, a physical vapor deposition (PVD) process, is the main thin film deposition method for manufacturing semiconductor, disk drive, CD and optical devices. The following are common problems in magnetron sputtering. We have listed possible causes and related solutions for your information. Here is a quick look that may save your time. Problem 1: The...Continue Reading
1. What types of coating technology can be divided into? (1) Vacuum coating (2) Electroplating (3) Chemical reaction (4) Heat treatment (5) Physical or mechanical treatment 2. What are the applications of plasma technology in surface technology? Sputter deposition: Sputtering is the use of high-speed ions to strike a solid sputter target, causing surface molecules...Continue Reading
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...Continue Reading
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...Continue Reading
Physical vapor deposition (PVD) and chemical vapor deposition (CVD) are considered to be the most attractive surface coating technologies and have a wide range of applications in various industries. Let us compare these two methods in detail. Physical Vapor Deposition Chemical Vapor Deposition Definition Physical vapor deposition (PVD) is a series of vacuum deposition methods...Continue Reading
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...Continue Reading
Tantalum Overview The texture of the tantalum is very hard and the hardness can reach 6-6.5. Its melting point is as high as 2996 °C, only after carbon, tungsten, rhenium, and osmium. Tantalum is malleable and can be drawn into a thin foil. Its coefficient of thermal expansion is very small, and it only expands by 6.6 parts...Continue Reading
