Precision glass molding (PGM) has been widely utilized in optical components production, during which binderless tungsten carbide (WC) is a popular mold material. Researchers have proposed the application of electroless nickel‑phosphorus (Ni–P) plating on WC molds, offering good surface finish, non-stick properties, and enhanced corrosion resistance, while typical Ni–P plating pretreatment is complex, time-consuming, carrying risks of surface damage and pollution. In this study, Atmospheric-pressure (AP) plasma surface processing has been proposed as an alternative pretreatment technique to enhance electroless Ni–P plating quality on binderless WC, contributing to the reduction of plating steps, time, smoothing of the plated Ni–P layer, and improvement in adhesion quality. The interaction mechanism between AP plasma and WC has been analyzed. The influence of AP plasma surface pretreatment on the surface quality of Ni–P plating has been investigated in detail. Surface characterization and adhesion test have been conducted to evaluate the effectiveness of AP plasma pretreatment method. Despite the fact the replication of substrate roughness exists in typical Ni–P plating process, the surface roughening and enhanced surface energy induced by AP plasma pretreatment can have a smoothing effect for the following electroless Ni–P plating process. The effectiveness of ICP AP plasma as an alternative pretreatment technique for high-quality electroless Ni–P plating on binderless WC has been validated.
