  • Patent number: 11661649
    Abstract: Disclosed are a component for a fuel injector and a method for coating the same. The component for the fuel injector may include a base material, a bonding layer laminated on the base material, a support layer laminated on the outer surface of the bonding layer, and an NbSiCN functional layer including an NbCN layer and an SiCN layer and alternately laminated on the outer surface of the support layer, thereby reducing friction, high hardness, shock resistance, heat resistance, and durability of the component for the fuel injector.

  • Publication number: 20210254206
    Abstract: A ball and a valve seat for a fuel injector, and a method for coating the same are provided to form a Ta—C:H—SiO functional layer having a low frictional characteristic as the outermost layer to reduce a frictional coefficient. A Mo-based material is applied to a bonding layer and a supporting layer for bonding and supporting the Ta—C:H—SiO functional layer is applied to a base material to improve heat resistance. Accordingly, only pure ionic Mo particles are deposited to form the bonding layer and the supporting layer, thereby increasing an adhesive force and a bonding force to improve durability.
