  • Coated valve components with corrosion resistant sliding surfaces
    Patent number: 11499643
    Abstract: A valve component comprising a substrate with a sliding surface, the sliding surface being designed to be subjected to sliding against another surface during operation of the valve, wherein at least a portion of the sliding surface is coated with a coating comprising an under-layer comprising tungsten and an upper-layer deposited atop the under-layer, said upper-layer comprising diamond-like-carbon, wherein the under-layer comprises carbon and has a layer thickness of at least 11 micrometers, and the upper-layer has a lower coefficient of friction than the under-layer and has a layer thickness of at least 1.5 micrometers.
    Type: Grant
    Filed: August 6, 2018
    Date of Patent: November 15, 2022

  • Decorative, jet-black coating
    Patent number: 9840779
    Abstract: A jet-black coating that resists wear; first, at least one DLC layer with a high degree of hardness is applied to a component and then a gradient layer, whose density decreases in the direction toward the surface, is applied to this DLC layer. By means of the refraction index progression that this produces in the gradient layer, the gradient layer functions as a reflection-reducing layer.

  • DLC coating with run-in layer
    Patent number: 9534291
    Abstract: A coating that resists wear; first, at least one DLC layer with a high degree of hardness is applied to a component and then a gradient layer, whose density decreases in the direction toward the surface, is applied to this DLC layer. By means of the hardness progression that this produces in the gradient layer, the gradient layer functions as a run-in layer in applications with sliding surfaces.
