Active Corrosion Protection Coatings |
| 摘要 |
The present invention is related to a method for protecting a metal substrate against corrosion comprising the step of: —generating a plasma in a gaseous medium by means of a plasma device; —placing the substrate in contact with the plasma, or in a post-plasma area of said plasma; —introducing in said plasma or in said post-plasma area a corrosion inhibitor along with an organic precursor, thereby depositing a barrier layer comprising the corrosion inhibitor, the deposited layer protecting the metal substrate against corrosion. |

1. Method for protecting a metal substrate against corrosion comprising the step of:
generating a plasma in a gaseous medium by means of a plasma device; placing the substrate in contact with the plasma, or in a post-plasma area of said plasma; introducing in said plasma or in said post-plasma area a corrosion inhibitor along with an organic precursor, thereby depositing a barrier layer comprising the corrosion inhibitor,the deposited layer protecting the metal substrate against corrosion wherein the corrosion inhibitor is gradually introduced in said plasma or in said post-plasma area thereby creating a concentration gradient of the corrosion inhibitor in the coating, the inhibitor concentration at the interface between the substrate and the barrier layer being lower than in the bulk of said barrier layer. |
