摘要 |
The invention concerns a method for continuously coating a moving substrate, preferably a steel metal strip, said coating deposited on the substrate comprising an ultrafine thickness between 20 and 2000 nm, and preferably between 40 and 500 nm. The invention is characterized in that the deposition is based on an aqueous solution containing oxide nanoparticles, and carried out in controlled pH conditions at high substrate temperature, preferably higher than 200 DEG C, the duration of the deposition being less than 10 seconds, and preferably less than 2 seconds. |
