The goal of this short tutorial is to define which materials are treatable by high vacuum deposition processes. This is an important issue for those approaching deposition processes for the first time, perhaps thinking of applying them to their products.

Diffusion pumps are static devices, that is, without moving mechanical parts, used as primary pumping devices in systems in which the required degree of vacuum is in the range between 1e-4 and 1e-9 mbar. These are the first devices developed capable of generating a pumping action in the so-called molecular vacuum regime, ie the one in which the free path of each molecule present in a closed chamber is greater than the size of the chamber itself.

In the world of high vacuum equipment, there is often a need to make fixed couplings between mechanical components that can guarantee the necessary sealing conditions between a low-pressure environment and the atmosphere. The most used standards nowadays, for the design of these couplings, are basically three: CF, KF and ISO. Let's see the general characteristics and the selection criteria.
