Beschreibung
Zusammenfassung:	The invention relates to a method of improving the corrosion resistance and reducing the friction coefficient of a metal or metal film-covered substrate. The inventive method consists in applying a coating to the aforementioned substrate, said coating comprising: a first layer which is obtained from one or a combination of partially-fluorinated alkanes bearing (i) at at least one end, a function that can adhere to the metal surface and (ii) a function that is compatible with a fluorinated lubricant; and a second surface layer which is obtained from a fluorinated lubricant. Pour améliorer la résistance à la corrosion et diminuer le coefficient de frottement d'un substrat métallique ou revétu d'un film métallique, on applique sur ledit substrat un revétement comprenant: - une première couche obtenue à partir d'un ou d'une combinaison d'alcanes partiellement fluorés portant d'une part, à au moins une extrémité, une fonction capable de réaliser un accrochage sur la surface métallique, et d'autre part une fonction compatible avec un lubrifiant fluoré ; - et une deuxième couche de surface obtenue à partir d'un lubrifiant fluoré.
