Plasma coating refers to a coating that has been deposited on a substrate surface using a plasma system. This plasma technology is used in a number of applications where a very thin and uniform film thickness is required. Common coating materials include chemicals such as silicon dioxide or silicon nitride as well as a variety of organic polymer forming species.... Plasma coating applications include coating objects with antiglare, dielectric, water repellent(hydrophobic), heat and chemical resistance coatings. A coating may be deposited on a variety of materials including metals, polymers and ceramics.

Facile à nettoyer : le revêtement fonctionnel qui repousse l'eau et les salissures. Le revêtement par plasma produit des surfaces très hydrophobes, c'est-à-dire qu'elles repoussent l'eau (effet lotus). [Les] domaines d'application pionniers sont le revêtement de pièces automobiles (par exemple, des jantes en aluminium) ou les fenêtres et les vitres.

Both anodic and cathodic effects are sometimes observed in the presence of organic inhibitors but, as a general rule, organic inhibitors affect the entire surface of a corroding metal when present in sufficient concentration. Organic inhibitors usually designated as "film-forming", protect the metal by forming a hydrophobic film on the metal surface. The effectiveness of these inhibitors depends on the chemical composition, their molecular structure, and their affinities for the metal surface. Because film formation is an adsorption process, the temperature and pressure in the system are important factors.

CONT

Les inhibiteurs organiques sont très nombreux, efficaces à des concentrations de quelques parties par million, agissent soit en augmentant la suspension d'hydrogène, soit en s'absorbant à la masse du métal pour constituer un film protecteur (inhibiteurs colloïdaux).

OBS

inhibiteur de corrosion : Produit chimique, minéral ou organique, que l'on ajoute en faible quantité à une solution corrosive en vue de diminuer ou d'arrêter son action sur un métal.
