Surface Finish
- martedì 31 agosto 2021
You may have noticed that the finishing of the internal surfaces of the vacuum chambers tends to be more and more accurate as the basic vacuum you want to obtain is more severe. The reason is that the amount of water that must be managed due to the outgassing phenomenon increases with the increase in the surface roughness of the chamber.
O-rings in high vacuum systems
- venerdì 18 giugno 2021
O-rings are fundamental elements of high vacuum systems. They are seals in elastomeric material, with a circular section, intended to be inserted in special seats, and to be compressed during use, acting as a sealing element.
Technical Gases in Vacuum Deposition Processes
- venerdì 23 aprile 2021
Many industrial vacuum deposition processes require an environment with a controlled composition of the environment: a certain amount of high purity technical gases is then continuously fed into the chambers, using controlled flow valves called MFC (Mass Flow Controllers).
Aluminum (and its alloys)
- giovedì 11 febbraio 2021
Aluminum, although not many know it, is a metal with extraordinary properties. It does not exist in nature in the metallic state, but always in the form of compounds, the best known of which is Bauxite, in which it is contained in the form of oxides and hydroxides.
The absolute emptiness
- venerdì 4 dicembre 2020
Absolute emptiness is the absence of matter in space. How many particles are present in the small UHV chambers used in laboratories? We asked ourselves this question in this article!
Oils in pumping systems for vacuum plants
- venerdì 23 ottobre 2020
In pumping systems for vacuum plants,, it is common to use rotary vane pumps. In these machines, the oil has important functions for the correct functioning of the machine.
Eliminate the water in a vacuum chamber by freezing it: is it possible?
- giovedì 8 ottobre 2020
The management of the "water load" in vacuum processing always represents a problem due to the molecular composition of the water. The use of cryogenic systems can help the elimination of the water present in vacuum deposition systems.
Vacuum: why?
- lunedì 6 luglio 2020
Vaccum processing needs the presencence of a particular environment. But why is a reduced pressure environment necessary and what are the pressures used in the vacuum technique? This are the reasons.
Stainless steel: why?
- lunedì 22 giugno 2020
If you have ever seen a machine for vacuum treatments, you will have noticed that the chamber in which the processing is carried out and a large part of the rest of the plant was made of stainless steel. But why, in these particular scientific and technological applications, is this material used? What are the advantages it offers (and what are the possible disadvantages)?
Magnetron Sputtering
- lunedì 9 settembre 2019
Magnetron sputtering has developed rapidly over the last twenty years, following the increasing industrial demand for high-quality functional films. Today, magnetron sputtering often outperforms other techniques used for the deposition of coatings of industrial interest.
