Basic Introduction
Electroless Nickel Plating (ENP) valve balls use an electroless plating process to form a nickel-phosphorus alloy layer with uniform thickness, high hardness, and strong corrosion resistance on the substrate surface. This process can achieve uniform plating on complex surfaces without the need for electricity, and has excellent wear resistance, corrosion resistance, and anti-galling properties. The process consistency is superior to electroplating nickel, making it suitable for harsh working conditions with mild to moderate corrosion and high wear resistance. It is a key sealing component in fluid sealing systems.
