The CVD process    
New materials, produced with chemical vapor deposition (CVD) are the core competences of PerCoTech.


In principle this technology works by evaporating a metal atom containing chemical compound that is fed into a vacuum furnace where the component to be coated is placed.


By the increased temperatures in the furnace the chemical compounds decompose and the desired metallic or ceramic layers are formed on the surface. These layers can be few 10 nanometers up to some hundred microns thick. Depending on request we can easily design special layer compositions for several appalications like catalysts etc. by mixing different educt compounds.

An enormous variety arises from this possibility to combine several educt compounds for certain applications of the CVD products. The only requirement for this method is that the materials to be coated are temperature consistent.

Thermal CVD processes are performed from at least 350°C and higher. Therefore the PerCoTech CVD Process needs only heat but no effortful plasma or laser generators, which are frequently used to support activated CVD processes. Cost-efficiency and an easy monitoring are the advantages of the PerCoTech CVD method. You can find a first overview about the chemical elements available for CVD in our periodic table.
