US 2019/0292678 A1 · DEPOSITION OF WEAR RESISTANT NICKEL-TUNGSTEN PLATING SYSTEMS

Abstract

Methods for depositing wear resistant NiW plating systems on metallic components are provided. In various embodiments, the method includes the step or process of preparing a NiW plating bath containing a particle suspension. The NiW plating bath is prepared by introducing wear resistant particles into the NiW plating path and adding at least one charged surfactant. The first type of wear resistant particles and the first charged surfactant may be contacted when introduced into the NiW plating bath or prior to introduction into the NiW plating bath. The at least one charged surfactant binds with the wear resistant particles to form a particle-surfactant complex. The wear resistant NiW plating system is then electrodeposited onto a surface of a component at least partially submerged in the NiW plating bath. The resulting wear resistant NiW plating system comprised of a NiW matrix in which the wear resistant particles are embedded.
