Morphologies and corrosion resistances of electroless Ni-P coated nanoporous coppers

Influence of Complexing Agents on Morphologies and Mechanical Properties of Nanoporous Copper/Nickel

“…As a sustainable non-noble nanoporous metal, nanoporous copper (NP-Cu) which can be prepared at low cost has attracted much attention due to the high electrical and thermal conductivity of copper [7,8]. Furthermore, the mechanical, corrosion resistance and catalytic properties can be improved by surface modification [9][10][11]. Electroless plating is a universal coating technique to improve the corrosion or wear resistance of various metals [12][13][14].…”

“…Nanoporous metals can be employed as electroless plating substrates due to their high surface activity. The catalytic properties, corrosion resistance, mechanical properties, and electrical and thermal conductivities of NP-Cu were improved by electroless plating of Pt, Ni, and Cu [9,10,15]. In addition, the appropriate use of complexing agents can not only improve the stability of plating solution, but also effectively regulate the coating deposition process and its performance [16][17][18].…”

“…In addition, the appropriate use of complexing agents can not only improve the stability of plating solution, but also effectively regulate the coating deposition process and its performance [16][17][18]. The previous report on the influence of electroless plating of Ni-P on the corrosion resistance of NP-Cu revealed that double complexing agent rather than single complexing agent (lactic acid, citric acid) was relatively suitable for preparing nanoporous copper/nickel (NP-Cu/Ni) [10]. In this research, the influence of concentration ratio of lactic acid to citric acid on the electroless plating process and mechanical properties of nanoporous copper is investigated.…”

Ni2+‐Assisted Dealloying Strategy to Prepare Nanoporous Cu–Ni Alloys with Enhanced Corrosion Resistance

“…[10][11][12][13] Nickel plating is used to enhance the corrosion resistance of NP-Cu. [14] Outstanding hydrogen evolution reaction performance is achieved through the formation of core-shell-like Cu@(Ni/NiO) ligaments. [15] In contrast, Cu-Ni alloys, also known as cupronickel, are widely used for marine applications because of their excellent resistance to seawater corrosion.…”
