Project summary: Sensofar brings optical innovation to European green project
March 26, 2025
Sensofar concludes its participation in the COMETA project with a successful prototype for industrial conversion coating treatment detection.
Sensofar has proudly concluded its participation in the European project COMETA, which focused on developing and validating Cr/P-free conversion coatings (CCs) for aluminum and steel. These new coatings are based on Zr-Ti formulations and corrosion inhibitors, offering an environmentally friendly alternative that complies with REACH regulations. The COMETA project aimed to replace traditional Cr(VI)-based treatments for aluminum and phosphate coatings for steel, addressing two critical issues: active corrosion protection and thickness control, both essential for proper paint adhesion and long-term performance.
As part of the consortium, Sensofar contributed by developing a compact and functional industrial prototype capable of detecting the presence or absence of conversion coatings on aluminum surfaces. The system works by projecting diffused light onto the sample and analyzing surface reflectivity to determine coating presence with high reliability. Thanks to its user-friendly software interface and compact design, the prototype is perfectly suited for on-site use in industrial environments, supporting more efficient and sustainable quality control processes.
The success of COMETA not only marks a technological advancement in corrosion protection but also highlights Sensofar’s commitment to sustainable innovation and its growing role in European research projects driving greener manufacturing solutions.
This project has been funded by CDTI, with the support of the Spanish Ministry of Science and Innovation, and co-funded by the European Union’s Eurostars programme.
