Abstract

La présente invention a pour objet un procédé pour revêtir une surface, notamment une jupe (7a, 7b) de piston (1) d'un moteur à combustion interne, d'un film (3) lubrifiant sec à haute résistance mécanique et à faible coefficient de frottement, destiné à réduire les frottements entre la jupe (7a, 7b) du piston (1) et le cylindre. Selon l'invention ce procédé consiste à : - Enduire la surface (7a, 7b) d'une pâte réalisée dans un solvant aqueux et comportant un polymère à faible coefficient de frottement ainsi qu'éventuellement des composés non organiques, - Chauffer ledit film (3) à une température T pendant une durée t, de manière à ce que ledit film (3) admette une structure amorphe.
