Coated cutting implements having increased longevity, corrosion and stain resistance, a smooth and uniform appearance and color, and/or reduced friction between cutting blades are provided. The coatings on the cutting implements have at least two layers. The first layer is a metal-based layer that imparts hardness or wear-resistance to the cutting implement. The second layer is comprised of an inorganic or organic polymer.
L'invention concerne des outils de coupe revêtus dont la longévité, la résistance à la corrosion et aux taches sont accrues, dont l'apparence et la couleur sont lisses et uniformes, et/ou dont la friction entre les lames de coupe est réduite. Les revêtements sur les outils de coupe comportent au moins deux couches. La première couche est une couche à base de métal qui confère dureté ou résistance à l'usure à l'outil de coupe. La deuxième couche est constituée d'un polymère inorganique ou organique.
