Vacuum deposition is a surface treatment used to deposit a material or alloy on a mechanical part.
The use of vacuum technology ensures a perfectly clean, non-polluting process.
It is not subject to REACH legislation.
The deposition method depends above all on the nature of the coating to be deposited and the substrate.
If the substrate cannot be heated to high temperature, the deposition must be carried out using low-temperature technology.
If the coating to be deposited consists of a solid element (metal or graphite target), a physical process such as PVD is used. If the coating consists of a gas or liquid, a chemical process such as CVD or PACVD is used.
This process greatly increases resistance to wear, abrasion, friction and corrosion. As a result, component life is greatly extended.
Standard thicknesses are of the order of 3µm and deposition is carried out on finished parts.
PVD is physical vapor deposition. The element to be deposited is obtained by evaporation or sputtering via a physical process. PACVD is plasma-assisted chemical vapor deposition. The element to be deposited is obtained from chemical reactions. Plasma enables this chemical reaction to take place at lower temperatures.
Nature of steel or carbide, if steel treated, please specify the treatments carried out. Desired characteristics (hardness), quantities of parts per shipment and per year, drawings of the part and specifications. If possible, how the part will be used and its final purpose.
