Study on the influence of technological parameters on the formation of a chemical nickel plating layer on fiberglass/polyamide composite

This study investigates the effects of temperature, plating time, and plating area-to-solution volume ratio on the formation of chemical nickel plating layers on fiberglass/polyamide composites. The experimental results demonstrate that optimal plating conditions are achieved at temperatures ranging from 75 to 80 °C. A minimum plating duration of 45 minutes is required to ensure adequate layer quality, characterized by electrical resistance ≤ 1.5 Ω and layer thickness ≥ 6 μm. Furthermore, the optimal plating area-to-solution volume ratio is determined to be within the range of 2.5:1 to 3.0:1 (dm²/L). These findings provide critical process parameters for achieving consistent and reliable chemical plating performance on composite substrates.
