Anodic dissolution of brass and dezincing-resistant brass investigated using channel flow double electrode

Analytical Study of CuZn 30 and CuZn 39 Brass Surfaces in 3% NaCl Solution Under Polarization

“…While a great deal of attention is paid to the determination of the corrosion parameters and the finding of different efficient inhibitors, a few studies have examined the brass crystal structure (alpha/alpha beta) effects on the mechanism of brass corrosion and, consequently, passive film evolution. A few papers deal with anodic dissolution and the mechanism of brass corrosion but without simultaneous characterization of the composition of the protective layer evolution [29,30], or in less aggressive media which involve other mechanisms [31,32]. Therefore, the aim of this paper is to study the behavior of CuZn alloys in the presence and absence of the beta phase in aggressive chloride media to explain the differences observed in their corrosion resistance.…”

Corrosion Electrochemical Kinetic Study of Copper in Acidic Solution using Scanning Electrochemical Microscopy

“…9,10 However, most of our knowledge about the corrosion kinetic of Cu focuses on the evolution of corrosion rate and the influence of environmental factors. 11,12 While, for the electrochemical reaction of O + ne − R, the fundamental equation of electrochemical kinetics is the Butler-Volmer equation, as following: 13 i = nFAk 0 C O(0,t ) e − a 1 nF RT (E −E 0 ) − C R(0,t ) e…”

Communication—Real-Time Surface Observation of Copper during Anodic Polarization with Channel Flow Double Electrode

“…1 The conditions of pit initiation and propagation on copper have been studied for several decades. 1,3,[5][6][7][8][9] The time resolved analytical technique 10 and hydrodynamic method [11][12][13][14][15] have been employed for the analysis of the anodic dissolution of copper. Zhou et al 10 measured the dissolution rate of copper directly and the scale formation indirectly from mass balance between the anodic current and the dissolution rate by an in situ atomic emission spectroelectrochemistry.…”

“…Zhou et al 10 measured the dissolution rate of copper directly and the scale formation indirectly from mass balance between the anodic current and the dissolution rate by an in situ atomic emission spectroelectrochemistry. Itagaki [11][12][13][14][15] applied a channel flow double electrode (CFDE) for investigation of the anodic dissolution mechanisms of copper and brass. In the CFDE system, the metallic ions dissolved from the working electrode (WE) can be detected by arranging a detecting electrode (DE) downstream of the WE.…”

“…In the CFDE system, the metallic ions dissolved from the working electrode (WE) can be detected by arranging a detecting electrode (DE) downstream of the WE. Itagaki et al [11][12][13][14][15] measured the anodic current of copper, i WE , and the dissolution current, i DE , of cuprous and cupric ions. They discussed the anodic dissolution mechanisms of copper and brass based on the dissolution efficiency of cuprous and cupric ions.…”
