Abstract
(EN)
A long-acting antibacterial solid lubricating film layer for a space environment and a preparation method therefor. The solid lubricating film layer comprises: a substrate, an Ag-containing diffusion layer, and a coating; the coating comprises: a Cr seed layer and an Ag-containing amorphous carbon film layer successively deposited on the substrate; the Ag-containing diffusion layer is located in the substrate adjacent to the Cr seed layer, and is formed from a matrix material and Ag atoms diffused and doped from the Cr seed layer into the matrix material. The Cr seed layer is deposited on the substrate, and then a magnetron co-sputtering graphite target and an Ag target are used to deposit a gradient transition Ag functional layer by means of adjusting and controlling the magnitude of a sputtering Ag current. Finally, heat treatment is performed to promote the diffusion of the Ag atoms in the coating to the substrate, thereby achieving an increase in the thickness of the Ag-containing antibacterial functional layer. After a long-term friction experiment, the obtained coating does not decrease in antibacterial level and achieves a long-acting antibacterial effect. The present invention is particularly suitable for a long-acting antibacterial lubrication component of a space station, and has large practical application requirements and good application prospects.

L'invention concerne une couche de film lubrifiant solide antibactérien à action durable destinée à un environnement spatial et un procédé de préparation associé. La couche de film lubrifiant solide comprend : un substrat, une couche de diffusion contenant de l'argent (Ag) et un revêtement ; le revêtement comprend : une couche de germes de chrome et une couche de film de carbone amorphe contenant de l'argent, déposées successivement sur le substrat ; la couche de diffusion contenant de l'argent est située dans le substrat adjacente à la couche de germes de chrome et est formée d'un matériau de matrice et d'atomes d'argent, diffusés et dopés de la couche de germes de chrome au matériau de matrice. La couche de germes de chrome est déposée sur le substrat puis une cible de graphite de co-pulvérisation par magnétron et une cible d'argent servent à déposer une couche fonctionnelle d'argent de transition de gradient par réglage et par commande de l'intensité d'un courant d'argent de pulvérisation. Enfin, un traitement thermique est effectué pour favoriser la diffusion des atomes d'argent dans le revêtement vers le substrat, ce qui permet d'obtenir une augmentation de l'épaisseur de la couche fonctionnelle antibactérienne contenant de l'argent. Après une expérience prolongée de frottement, le niveau antibactérien du revêtement obtenu ne diminue pas et atteint un effet antibactérien à action durable. La présente invention s'avère particulièrement appropriée pour un élément de lubrification antibactérien à action durable d'une station spatiale et répond à de grandes exigences d'application pratiques et à de bonnes perspectives d'application.
