| 摘要 |
The invention concerns a method for continuously coating a moving substrate such as a steel metal strip, the coating formed being an ultrafine film of thickness ranging between 10 and 100 nm, deposited on the substrate: from a solution containing oxide nanoparticles, under controlled pH conditions, said substrate being at a temperature higher than 120 DEG C, the total duration of deposition being less than 5 seconds, and preferably less than 1 second. The invention is characterized in that at least one chemical additive, called refiner, is incorporated in said solution, said refiner having, reciprocally, an antagonistic effect relative to the formation of said coating. |
