Devices with a moveable component that includes a coated surface are described. In some examples, the moveable component can contact a functional fluid during movement of the moveable component. The moveable component includes a coated surface with a surface coating comprising an alloy layer. The alloy layer comprises molybdenum or tungsten in combination with one or more other materials. L'invention concerne des dispositifs comprenant un composant mobile qui comprend une surface revêtue. Dans certains exemples, le composant mobile peut entrer en contact avec un fluide fonctionnel pendant le mouvement du composant mobile. Le composant mobile comprend une surface revêtue avec un revêtement de surface comprenant une couche d'alliage. La couche d'alliage comprend du molybdène ou du tungstène en combinaison avec un ou plusieurs autres matériaux.
