Beschreibung
Zusammenfassung:	Improving the corrosion resistance and reducing the coefficient of friction of a metal or metal-coated substrate comprises applying a layer of coupling agent (I) and a layer of fluorinated lubricant (II), where (I) is a partially fluorinated alkane with a terminal metal-bonding function and a function compatible with (II). Pour améliorer la résistance à la corrosion et diminuer le coefficient de frottement d'un substrat, on applique sur ledit substrat préalablement revêtu d'un film conducteur un revêtement comprenant :- une première couche intermédiaire obtenue à partir d'un alcane partiellement perfluoré portant d'une part une fonction capable de réaliser un accrochage sur le film conducteur et d'autre part une fonction capable de réagir avec un lubrifiant polyéther perfluoré;- et une deuxième couche de surface obtenue à partir d'un lubrifiant polyéther perfluoré.
