“…The aqueous and gaseous oxidation rates of alloys frequently depend on crystallographic orientation, − but a comprehensive understanding of the reaction pathways is rarely established owing to significant experimental challenges, especially when considering orientations far away from low-index surfaces. More attention has historically been paid to the impact of crystallographic orientation on gaseous oxidation, − motivated by the relevance of oxide surfaces as catalyst supports.…”

The effects of crystal orientation and prior etching on the polarization and repassivation behavior of Ni–Cr and Ni–Cr–Mo alloys have been investigated in acidic chloride environment using dc potentiostatic and ac single-frequency electrochemical impedance spectroscopy. Tests were conducted within the passive region at potentials where local oxide breakdown was possible. Surface morphologies of grains across a wide range of orientations were measured before and after passivation using atomic force microscopy. Oxide growth was monitored on isolated low- and high-index crystallographic planes as a function of repassivation time, enabling the independent measurement of the oxidation and total anodic current densities. Grains exhibited the tendency to either passivate with significant or minimal oxidation or instead resist active passivation and repassivation. The oxidation performance was a function of the crystallographic orientation of the exposed grain surface. The oxides grown on various-orientated surfaces differed in their film growth kinetics, morphology, and steady state thicknesses, even given similar total anodic current densities due to dissimilar oxidation efficiencies. For Ni-11 wt % Cr, only orientations close to (1 0 1) were able to form stable passive films, aided by nanofaceted surfaces with a matchstick-type morphology. On the other hand, all orientations of the Ni-11 wt % Cr-6 wt % Mo alloys formed electrochemically stable oxides films owing to the beneficial influence of Mo on repassivation. Passivation, breakdown behavior, and oxide properties vary with crystal orientation, and this work provides insight into the effects of crystallographic orientation and oxide film morphology on the passivation mechanism of Ni–Cr and Ni–Cr–Mo alloys.

“…The XRD patterns show that both the electrodeposited Cu and Ni foils are (111) preferred textured. Studies show that (111) textured Ni and Cu foils possess higher corrosion resistance 8,9,13,37 , which is understandable since the (111) plane has the lowest surface energy, corresponding to the highest surface stability.…”

“…For realistic applications, it is vital to know the stability of Cu and Ni in different environments and corresponding mechanisms. The frequent corrosion mode of Cu and Ni is atmospheric corrosion, which has been broadly investigated [7][8][9][10][11][12][13][14] . Many studies on corrosion of Cu and Ni in NaCl solutions have also been carried out, since NaCl is one of important aggressive media, which has impact on corrosion of metals especially in ocean environment 9,10 .…”

“…In combination with morphological analysis in section "Morphology and microstructure of corrosion products", the longer fibers contain more Cu 2 O in the oxide film formed under UV irradiation, which is more protective against mechanical and electrochemical attacks. As a result, the corrosion resistance of Cu foil in 3.5% NaCl solution is improved after being illuminated by the UV light 13 . Meanwhile, studies showed that the oxide scale on Cu alloys containing appropriate amounts of Cu(OH) 2 exhibited better anti-corrosion property 52,53 in neutral environment.…”

Influence of ultraviolet (UV) light irradiation on the corrosion behavior of electrodeposited Ni and Cu nanocrystalline foils in 3.5% NaCl solution was studied by means of electrochemical methods, electron work function (EWF) analysis, and characterization with atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). It was demonstrated that the influence of solar light on corrosion of the metals was non-negligible, which could be very different for different materials. The UV light irradiation resulted in an increase in corrosion resistance of the Cu foil but showed an opposite influence on that of the Ni foil. Based on surface state analysis, it was concluded that the UV irradiation altered the surface oxide films. The UV light induced the formation of Cu2O on Cu, which is more stable and compacted than naturally formed CuO film. However, the UV light accelerated the formation of Ni2O3, which is loose, porous and brittle, compared to naturally formed NiO on Ni. The changes in oxide films were responsible for the opposite variations in the corrosion behavior of the Cu and Ni nanocrystalline foils caused by the UV light irradiation.

“…The initial Cu foils were manufactured by rolling and therefore low levels of oil were present upon the surface, this caused adhesion issues, and therefore needed to be removed before use [81]. More recently Cu foils are manufactured by electrodeposition methods [82]. Apart from the good electrochemical stability aforementioned, Cu is the second most conductive metal with a resistivity of 1.68 x 10 -8 Ωm at 20 ˚C [48], which is another advantage of using Cu current collectors.…”
