摘要

Process for obtaining coatings by automatic airbrushing technique from suspensions of nanometric powders or sols obtained via sol-gel, and device for tuning.; The procedure of the preparation of nanometric powder by a chemical route, then proceed to the preparation of the slurry or ink from the nanoparticulate powder. Then the coating is performed by automatic airbrushing. This procedure allows the production of layers or catalytic coatings for the development of electrodes for fuel cells using this technique automatic airbrushing. For airbrushing an airbrush (1) incorporated in a rail (2) moving along a triangular wave, activated by a wave generator (3) and assisted by a compressor (4) to generate a projection is used (5 ) Pt on a substrate of C.
