Corrosion Resistance and Wettability of Selective Plated Copper-based Coatings Containing Silver Particles

Abstract

This study investigates the corrosion resistance and wettability of selective plated copper-based coatings incorporating silver particles. The coatings were deposited onto 316L stainless steel substrates, and the effects of silver particle size and electrolyte composition on the surface topography and corrosion behaviour were examined. Changes in the wettability of the coatings were evaluated by measuring the water contact angle on the coated surfaces. The results revealed that coatings obtained from an alkaline electrolyte containing silver particles exhibited a lower corrosion rate, whereas those produced from an acidic electrolyte demonstrated a higher contact angle.
