Surface analysis of 2-mercaptobenzothiazole (MBTH) adsorbed on brass from 3 wt.% NaCl solution was performed by means of X-ray photoelectron spectroscopy and tandem (MS/MS) time-of-flight secondary ion mass spectrometry (ToF-SIMS). These surface analytical techniques were used in association with the gas cluster ion beam (GCIB) sputtering method at various acceleration energies and cluster sizes, which slowly removes the surface layer and leaves the chemical information intact during the sputtering of the very thin surface layer. In addition, MS1 ToF-SIMS was used for 2D and 3D imaging to show the molecular and elemental distribution of the surface species. Using the tandem ToF-SIMS capability, the MS2 spectra clearly confirmed the presence of MBTH on the surface. Moreover, organometallic complexes were indicated, which formed between the MBTH and Cu ions released due to the corrosion of the brass. These analyses were performed based on the fragmentation products identified in the MS2 spectra.

“…1,[4][5][6][7][8][9][10][11][12] In this work, the influence of the amino group in 1,2,4-triazole (TRI) in position 3, that is, 3-amino-1,2,4-triazole (3-AT) ( Figures 1A and 1E), is investigated in detail to explain whether and why it has an influence on the corrosion inhibition effect for brass in 3 wt.% NaCl solution. Brass is generally an important material for various applications [13][14][15][16][17][18][19][20][21][22][23] but corrodes considerably in chloride-containing solutions. [24][25][26][27] Initially, the corrosion inhibition effect was determined after short-and long-term immersion periods (from 1 h to 31 days) using electrochemical techniques (electrochemical impedance spectroscopy, EIS, and potentiodynamic curve measurements), 3D profilometry, and atomic force microscopy (AFM).…”

Rationale The detailed surface analysis of corrosion inhibitor surface layers by the application of 1,2,4‐triazole (TRI) and 3‐amino‐1,2,4‐triazole (3‐AT) compounds adsorbed from a 3 wt. % NaCl solution on the brass surface was performed by time‐of‐flight secondary ion mass spectrometry (ToF‐SIMS). The results obtained were additionally supported by X‐ray photoelectron spectroscopy (XPS) measurements. Methods The description of the corrosion inhibitor surface layers was elaborated by using ToF‐SIMS and molecular‐specific signals. Characteristic molecular‐specific signals were used to perform 2D ToF‐SIMS imaging and cooling/heating experiment associated with ToF‐SIMS measurements. A detailed surface analysis using high‐resolution angle‐resolved XPS and gas cluster ion beam sputtering in combination with XPS measurements was also carried out. Results Organometallic complexes were formed after the corrosion process of brass with the release of Cu and Zn ions that subsequently connect with TRI or 3‐AT. Using ToF‐SIMS, possible spectral interferences of the organometallic species were considered due to the presence of different organometallic compounds composed of the two main Cu and Zn isotopes, that is, 63Cu and 65Cu and 64Zn and 66Zn. Using the molecular‐specific signals, 2D imaging was performed, which showed a different distribution of different species on the brass surface. In addition, a ToF‐SIMS experiment on thermal stability showed that most of the TRI‐ and 3‐AT‐related species desorb from the brass surface at 460 °C and 405 °C, respectively. Conclusions ToF‐SIMS analysis confirmed the formation of Cu/Zn‐ or Cu2‐inhibitor organometallic complexes, whereas the formation of Zn2‐inhibitor organometallic complexes on the brass surface was not confirmed. ToF‐SIMS imaging showed complete coverage of the brass surface with different Cu/Zn‐ or Cu2‐inhibitor organometallic complexes. The high thermal stability of the corrosion inhibitor surface layers was confirmed by ToF‐SIMS.

“…Brass alloys (Cu-Zn) have been regarded as commercial alloys. This alloy is one of the familiar candidates for electrical structure, pipe and valve industries due to its excellent thermal and electrical conductivity and appropriate corrosion resistance properties [1][2][3]. The previous studies demonstrated that the corrosion resistance of the brass alloys is severely dependent on the value of Zinc [4,5].…”

This study's main purpose is to achieve an optimal hot-dip coating condition of Sn-Sb for an α-brass alloy. Therefore, the hot-dipping parameters, including pre-flux lubricants, immersion temperature, time, and withdrawal speed were investigated. ZnCl2 and SnCl2 were used as pre-flux bath additives. The temperature of the immersion bath was selected to be in the range of 250-300 °C. Also, the exposing time and withdrawal speed of the specimens during the hot-dipping process were in the range of 10-60 sec and 254-1524 mm/min, respectively. Visual inspection of the coating revealed that by using SnCl2 as a pre-flux additive, high-quality smooth coating is achieved. According to the AFM result, the initial roughness value of the substrate was 450 nm. The coating's roughness value with SnCl2 and SnCl2+ZnCl2 pre-fluxes were in the range of 300-500 and 700-900 nm, respectively. Therefore, ZnCl2 pre-flux is associated with a rougher surface. Corrosion test analysis revealed that both coating condition with different pre-fluxes leads to increasing corrosion resistance however better improvement in corrosion behavior is accomplished by smooth coating surface. The quantitative analysis of the polarization curve revealed that the corrosion rate of the smooth coating is decreased 7-12.5 times in comparison with the substrate. According to the SEM analysis, the predominant phases which were appeared at the interface of the coating and substrate were Cu3Sn and Cu6Sn5. SEM analysis revealed that the Cu3Sn intermetallic compound was this first phase, which was promoted near to the substrate vicinity during the hot-dipping process.
