FLUID TIGHT LOW FRICTION COATING SYSTEMS FOR DYNAMICALLY ENGAGING LOAD BEARING SURFACES

A protective coating system is described that is characterized by fluid impermeability and a reduced coefficient of friction. The coating system includes a carbide-based thermal spray composition; a low friction layer; and a sealant impregnated into the low friction layer. Unlike conventional materi...

Beschreibung
Zusammenfassung:	A protective coating system is described that is characterized by fluid impermeability and a reduced coefficient of friction. The coating system includes a carbide-based thermal spray composition; a low friction layer; and a sealant impregnated into the low friction layer. Unlike conventional materials, the coating systems of the present invention achieve and maintain sealing surfaces, without adversely impacting lubricity, wear resistance and corrosion resistance during the service life of the coated component. La présente invention concerne un système de revêtement protecteur qui est caractérisé par une imperméabilité aux fluides et un coefficient de frottement réduit. Le système de revêtement comprend une composition de pulvérisation thermique à base de carbure ; une couche à faible frottement ; et un agent d'étanchéité imprégné dans la couche à faible frottement. Contrairement aux matériaux classiques, les systèmes de revêtement de la présente invention obtiennent et maintiennent des surfaces d'étanchéité, sans avoir d'effet négatif sur le pouvoir lubrifiant, la résistance à l'usure et la résistance à la corrosion pendant la durée de vie du composant revêtu.
