copper nickel solutions

  • Effect of Nickel Content on the Corrosion and Passivation of Copper

    The effect of Ni content on the corrosion and passivation behaviors of coppernickel alloys with different Cu to Ni ratios was investigated in neutral sulfate solutions. The influence of working conditions (e.g., immersion time, sulfate ions concentration, and temperature) on the electrochemical behavior of the different alloys

  • Dissolution of copper and coppernickel alloys in aerated dilute HCl

    Sep 1, 2000 The nickel of the alloys dissolves simultaneously, but in quantities higher than present in the solid metal. Air oxidizes Cu+ to Cu2+. When enough of Cu2+ accumulates in solution, the dissolution of Cu is autoalyzed through the reaction Cu+Cu2+=2Cu+. This conclusion is supported by the results of

  • Electrochemical behavior of copper–nickel alloys in acidic chloride

    The anodic dissolution of the Cu–10Ni alloy in HCl solutions was controlled by both mass transfer and reaction activation in the apparent Tafel region [4–6,8]. The mechanism for the alloy dissolution is controlled by the dissolution of the copper from the alloy. Study of the electrodissolution of Cu–Ni alloys in 1.0 M HCl
