Pressure Gauges

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Pressure Gauges Pressure, force per unit area (N/m2), is identified as the applied force by a fluid (gas or liquid) to a surface. Pressure measurement has many applications in everyday life. For decades, tools used to measure and display pressure are known as Pressure Gauges or Vacuum Gauges. A vacuum gauge can measure the pressure ranges lower than the ambient pressure. Generally, the pressure is not an absolute quantity, and most pressure gauges determine the pressure compared to the atmospheric pressure as the reference.

Vacuum Plasma | Vacuum Plasma Treatment

Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] What Is Vacuum Plasma Treatment? Plasma as the fourth state of matter introduced in 1927 by Langmuir, is observable in various places, from Vacuum plasma in a glow discharge tube in a lab to lightning and flames in the atmospheric presuure. Vacuum plasma treatment is a common method for creating surfaces with desired properties through coating, cleaning, etching, surface activation and functionalization. Plasma can be generated by applying an electric current across a dielectric gas (arcing) or increasing the gas temperature by heating (like a flame) to take out the electrons from atoms and ionizing the gas, making it conductive. These charged particles can affect the electrical characteristics of the gas or be manipulated by external electric/magnetic fields.

Glow discharge happens when free plasma electrons recombines with positive ions and emit photons. This phenomenon lies between the dark discharge region with low current ionization and no light emission, and arc discharge with large radiations (Figure 1). Glow discharge plasma contains energetic ionized gases species, which can be used for different purposes, cleaning a surface or coating it, as sputtering deposition method.

Physical Vapor Deposition (PVD)

Deposition, Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text] Physical Vapor Deposition (PVD) Physical Vapor Deposition (PVD) is a set of vacuum deposition methods in which a solid material vaporizes in a vacuum environment and is deposit on the substrate as a thin film. The most common methods of PVD are Sputtering and Thermal Evaporation. Because in the PVD process, the material is transported and accumulated atom-by-atom or molecule by molecule in a vacuum to the substrate surface, the deposited films have high purity and efficiency that for many applications compared to other deposition methods are preferred.

Chemical Vapor Deposition (CVD)

Deposition, Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner][vc_column_text css=""] Chemical Vapor Deposition (CVD) Chemical Vapor Deposition (CVD) is a chemical process used to create layers with different applications on different surfaces. In this deposition method, the desired surface (substrate) is exposed to the vapor of one or more chemicals. Then, in order to create a solid layer with the desired chemical composition, the gas atoms in the chamber decompose on the surface of the substrate or react with each other chemically. This deposition method is classified in different ways depending on what chemical method it starts with.

Deposition Methods | Vacuum Deposition

Deposition, Report

[vc_row][vc_column width="3/4"][vc_row_inner][vc_column_inner width="1/2"][vc_column_text css=""] What is Deposition? Deposition processes help to create thin or thick layers of a substance, established atom-by-atom or molecule by molecule on a solid surface. The created layer during a deposition process serves as a coating on a surface and changes the properties of the substrate surface depending on the application. The thickness of the deposited layers in this process can be in the range of one atom (Nanometer) to several millimeters, depending on the coating method and the type of material. Several methods exist for creating a layer of different materials on different surfaces. These methods are mainly categorized based on deposition physics, like the source phase, which can be the vapor or solution phase of the source material. Why Deposition? It has many advantages…
