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
AlxCr1-xN coatings have excellent mechanical properties and oxidation resistance and are therefore of high application value in a variety of industrial applications. In recent years, the effects of various deposition parameters (such as partial pressure, gas mixture or temperature) on the sputtering process have been studied, but there has been little research on the influence...Continue Reading
Transparent conductive films have many applications, and indium tin oxide films have received great attention in the glass manufacturing industry due to their excellent properties. However, the manufacturing process of the indium tin oxide film requires a higher temperature, which limits its application. In order to reduce this temperature, various “sintering agents” have been taken...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 PVD is a series of vacuum deposition methods that produce films...Continue Reading
We have previously made a brief introduction of Five Sputter Coating Technologies, including unbalanced magnetron sputtering, radio frequency sputtering (RF sputtering), direct current magnetron sputtering (DC sputtering), mid-frequency alternating current magnetron sputtering (AC sputtering), and reactive magnetron sputtering. In this article, we are going to talk about direct current (DC) sputtering in detail. To begin...Continue Reading
Due to their excellent wear resistance, heat resistance and other properties, PVD coatings are widely used in various industries. However, the defects of the coating make it impossible to demonstrate all of its advantages. If you want to solve the defects in PVD coating, you must know these defects, at least you should know – what...Continue Reading
What is PVD Coating Technology? Physical Vapor Deposition (PVD) is a thin film preparation technique that physically vaporizes the surface of a material source (solid or liquid) into gaseous atoms, molecules, or partially ionized into ions under vacuum conditions. Then, a film having a specific function is deposited on the surface of the substrate by...Continue Reading
Unbalanced magnetron sputtering Unbalanced magnetron sputtering uses an unbalanced magnetron sputtering cathode, which refers to the unequal magnetic fluxes of the inner and outer magnetic pole sections of the cathode. The effect of the unbalanced magnetic field is to trap fast-moving secondary electrons that escape from the target surface. These electrons undergo ionizing collisions with...Continue Reading
