Electrochemical Evidence of Corrosion Resistance of Polyaniline Film on the Copper Surface

A novel and simple method to improve the corrosion resistance of copper by constructing a three-dimensional (3D) 1-dodecanethiol self-assembled monolayer (SAM) in 3.5% NaCl solution is reported in this study. Several drops of 1% H3PO4 solution are thinly and uniformly distributed on copper surface to form a 3D nanostructure constituted by Cu3(PO4)2 nanoflowers. The anticorrosion properties of 1-dodecanethiol SAM on copper surface and on copper surface that is treated with H3PO4 solution were evaluated. Results demonstrated that 1-dodecanethiol SAM on bare copper surface exhibits good protection capacity, whereas a copper surface that is pretreated with H3PO4 solution can substantially enhance the corrosion resistance of 1-dodecanethiol SAM.

In this study, the anti-corrosion properties of nickel-based coatings on the surface of copper alloy were investigated, and damages caused by corrosion on the copper surface were resolved. Researchers prepared nickel-based coatings by supersonic particles deposition, and tested the anti-corrosion properties of brass substrate and nickel-based coating by electrochemical technology and neutral salt spray. The results show that, the corrosion current of coating decreased 35 times than that of matrix. The successive and pyknotic oxide film on the surface of coating prevented reaction of corrosion further. When it reached 500 hours, the corrosion rate closed to 0. Nickel-based coatings prepared by supersonic particles deposition contribute to the increase of corrosion resistance significantly, which verifies that it is feasible to prepare outstanding corrosion resisting nickel-based coating by supersonic particles deposition.

Coating Roughness

Effects of copper surface roughness [Formula: see text] on the properties of Ni–Co–Fe alloy coatings were studied by the measurement of coating roughness, thickness, hardness, substrate/coating bonding force and the potentiodynamic polarization curve. Results showed that at the current density of 4[Formula: see text]A/dm2, the coating roughness increased with the increase of the value of substrate [Formula: see text] in the range 0.1–1.1[Formula: see text][Formula: see text]m. The coating thickness and hardness increased with the decrease of substrate [Formula: see text]. When substrate [Formula: see text] was 0.4[Formula: see text][Formula: see text]m, the substrate/coating bonding force reached the maximum level. When substrate [Formula: see text] was 0.1[Formula: see text][Formula: see text]m, the coating exhibited the best corrosion resistance. The comprehensive properties of the Ni–Co–Fe coatings can be effectively improved by controlling the surface roughness of copper substrate properly.
