Abstract (en)
Coatings containing nickel-tungsten (NiW) plating layers are provided, as are methods for forming coatings and NiW plating layers over metallic components. In embodiments, the method includes preparing a plating bath containing a tungsten (W) ion source; inserting at least one consumable nickel (Ni) electrode and at least a portion of the metallic component into the plating bath; and, afterwards, electrodepositing a NiW plating layer over the component surface by energizing the at least one consumable Ni electrode as an anode and the metallic component as a cathode to attract Ni ions and W ions to the component surface. An amount of anode corrosion accelerant in the plating bath is controlled to balance Ni dissolution at the anode to Ni deposition at cathode, as considered in conjunction with any additional Ni ion sources within the plating bath, to achieve a desired composition of the electrodeposited NiW layer.
