- Vacuum Deposition: CITRA is equipped with a magnetron type PVD/PECVD able to work up to 300 °C. Coating can be carried out on metallic, ceramics or polymer substrate, owning to the flexibility to adapt the tooling and the machine to the client’s needs.

- Wet Process: CITRA offers coating solutions via electroplating and electroless process. Thanks to the flexibility of the CITRA pilot’s plant containing 30 tanks of 80 L, any development
request can be considered ; from the application of new commercial formulations to the development of specific preparation steps.

- Characterization: Among its activities, CITRA offers laboratory services for the characterizations, analyses and expertise on coatings and bulk materials. It relies on strong partnerships with its nearby
ecosystem (IRCER laboratory, ENSIL-ENSCI) in order to complete its characterizations offer thanks to the pooling of specific equipments.



CITRA offers dedicated industrial facilities for coating developments and their characterizaton. In addition of its R&D studies, it offers custom-made training and technical assistance.
