Behavior of WC-Ni Bushings in Chloride-Rich Water","og_description":"WC-Ni (tungsten carbide\u2013nickel) bushings are widely used in pumps, valves, and rotating equipment because they offer strong wear resistance and good toughness. But in chloride-rich water, such as seawater or chemical process fluids, corrosion becomes a major concern. This article explains how WC-Ni bushings behave in chloride environments, what factors drive corrosion, and how to improve their service life in demanding applications. What Are WC-Ni Bushings? WC-Ni bushings are a type of tungsten carbide composite, where nickel acts as the binder material, providing toughness and enhancing the material&#8217;s ability to withstand mechanical stress. Tungsten carbide (WC) is extremely hard, offering excellent wear resistance, while the nickel binder improves the overall
