Effect of Cu in electroless Ni–Cu–P coating on passivation process

Abstract: Electroless Ni-P and Ni-Cu-P coatings were passivated by chromate conversion treatment respectively. The anticorrosive performances of passivated coatings were investigated by potentiodynamic polarization and electrochemical impedance spectroscopy measurements. The passivated Ni-Cu-P coating exhibited a high corrosion resistance with the i corr of 0.236 μA/cm, 2 while the value of passivated Ni-P coating was only 1.030 μA/cm, 2 indicating the passive film could improve the corrosion resistance of Ni-Cu-P coati… Show more

“…In order to further improve its performance, researchers hoped by adding a third element in the bath during electroless plating to reach this purpose [3]. In specific, the elements or particles such as Fe [4], Si 3 N 4 [5], Cu [6], TiO 2 [7] were introduced into the metal coating to improve its hardness, wear resistance, self-lubricating property and corrosion resistance, etc. [8][9][10].…”

“…those that can be deposited individually and those that can be only codeposited. The former group consists of metals that are much nobler than Ni, like Ag [54][55][56][57] and Cu [58][59][60][61][62][63][64][65][66][67][68]; metals that have similar standard potentials, such as Co [69][70][71][72][73][74][75][76] and Sn [77][78][79][80][81][82][83][84][85]; and metals that are more cathodic, like Cr [86,87], Zn [88][89][90][91][92][93][94][95][96][97][98][99][100] and Mn [101]…”
