CVD coating

Chemical vapor deposition (CVD) is a highly developed coating technology in which solid materials are deposited from gaseous precursors on a highly heated surface by means of chemical reactions. In this refined form, the components are extremely resistant to breakage and suitable for insulation. 

How does the CVD coating process work?

In CVD coating, precursor gases are introduced into a reactor where they encounter hot substrate surfaces. The high temperatures in the reactor initiate a chemical reaction of the gases, whereby the resulting solids are deposited on the substrate as a thin layer.  

The process takes place under controlled conditions of temperature and pressure to ensure optimum coating properties. The process typically takes place at temperatures between 700 and 1000°C, resulting in high-quality, pure and optimally adhering coatings. 

Excess gases and reaction by-products are safely extracted and neutralized to meet environmental standards such as ATEX directives and TA Luft. CVD is applied in various forms such as low pressure CVD (LPCVD), which operates under reduced pressure to further improve the uniformity and quality of coatings.

Far-reaching potential of CVD coating for modern industry

CVD technology is widely used in numerous industries, from semiconductor manufacturing to aerospace and biomedicine. Used in these industries, this form of surface finishing offers decisive advantages: 

• Improved material performance through CVD coatings that resist corrosion, wear and thermal degradation 
• High purity and adhesion, as the chemical reactions ensure pure coatings with excellent adhesion to substrates 
• Tailor-made properties by varying the process parameters, enabling specific coating compositions and properties 
• Innovative applications from the semiconductor industry for the production of circuits to medical technology for biocompatible coatings 
• Sustainability through efficient use of resources and emission control, whereby CVD technology supports environmentally friendly production processes 

Thanks to these properties, CVD coating opens up new possibilities for high-performance materials that can be used under extreme conditions and contributes to innovation and increased efficiency in many technological areas.
