NiPW is a nickel-phosphorus-tungsten composite or electrodeposited coating material that combines the corrosion resistance and hardness of nickel-based systems with tungsten and phosphorus reinforcement. This material family is used primarily in wear-resistant coatings, hydraulic systems, and precision components where both durability and chemical resistance are critical; it offers a middle ground between conventional nickel plating and harder but more brittle ceramic coatings. The tungsten-phosphorus alloying approach is notable for its ability to maintain toughness while achieving high surface hardness, making it preferable in applications that experience both mechanical wear and corrosive exposure.
