“…The ASTM G119 standard has been widely used to quantify the synergism of a large number of materials in different environments [33,34,[109][110][111][112][113][114][115][116][117]. Neville and Hu (2001) [118] performed erosion-corrosion tests and observed that the resistance to material loss did not increase with the increase in hardness of the studied alloy, since corrosion was found to have an important synergistic effect on erosion.…”

This paper reviews the most recent available literature relating to the electrochemical techniques and test procedures employed to assess tribocorrosion behaviour of passive materials. Over the last few decades, interest in tribocorrosion studies has notably increased, and several electrochemical techniques have been adapted to be applied on tribocorrosion research. Until 2016, the only existing standard to study tribocorrosion and to determine the synergism between wear and corrosion was the ASTM G119. In 2016, the UNE 112086 standard was developed, based on a test protocol suggested by several authors to address the drawbacks of the ASTM G119 standard. Current knowledge on tribocorrosion has been acquired by combining different electrochemical techniques. This work compiles different test procedures and a combination of electrochemical techniques used by noteworthy researchers to assess tribocorrosion behaviour of passive materials. A brief insight is also provided into the electrochemical techniques and studies made by tribocorrosion researchers.

“…At low annealing temperature for short holding time, there are still more structure defects and residual stress in Cu-30Ni alloy tube so that the seawater corrosion resistance is mostly correlative to prior cold work. This may be explained as follows: the prior cold work enhance corrosion of copper alloy in the NaCl solution because the prior cold work increase the dislocation density and thus lead to higher stored strain energy, which can increase the driving force for corrosion (Yin and Li, 2005;Scully, 1990). However, from Figs.…”

“…Depending on tube material, the failures may result from H 2 S or NH 3 polluted seawater (Beccaria et al, ting attack (Shams El Din and Mohammed, 1998;Al-Malahy and Hodgkiess, 2003;El-Dahshan et al, 2003). However, in the same marine environment, the corrosion resistance of Cu-Ni alloy is concerned with chemical composition, microstructure, original surface film and residual stress (Constantinides et al, 2002;Yuan and Pehkonen, 2007;Lin and Zhao, 2000;Yin and Li, 2005). It is well known that the bright annealing is the last production process for manufacturing Cu-Ni alloy tube, thus it can be considered that annealing treatments after cold drawing play an important role on the levels of microstructure and properties of Cu-Ni alloy.…”

An Investigation on Dislocation Density in Cold-Rolled Copper Using Electrochemical Impedance Spectroscopy

et al. 2013

Variation of electrochemical impedance with dislocation density was investigated using electrochemical impedance spectroscopy (EIS). For this purpose, EIS measurements were carried out on 10, 20, 30, 40, and 50% cold-rolled commercially pure copper in 0.1 M NaCl (pH = 2) solution. Nyquist plots illustrated that the electrochemical reactions are controlled by both charge transfer and diffusion process. Increasing dislocation density, the magnitude of electrochemical impedance of samples was decreased. Decreasing magnitude of impedance at intermediate frequencies indicated increasing double-layer capacitance. Charge transfer resistance decreased from value 329.6 Ωcm 2 for annealed sample to 186.3 Ωcm 2 for sample with maximum dislocation density (1.72 × 10 15 m −2 ). Phase angles were lower for samples that contained more dislocation density, indicating more tendencies to loss of electrons and releasing atoms into electrolyte.
