Dec 1, 2014 · The surface of brass (Cu80/Zn20) exposed in water and different aqueous solutions and 2-mercaptobenzothiazole (MBT) is studied by XPS. The leaching of zinc (dezincification) is observed in pure water and in borate solutions.

Jan 1, 2023 · It is found that MBT forms multilayers on Cu oxide and inhibits the oxide layer growth. The XPS data are consistent with MBT adsorbed on oxide in multilayers, with a small fraction adsorbed on metallic Cu. These interactions …

Jan 1, 2023 · The XPS data show that the MBT molecule is adsorbed on copper oxide, with binding energies of 399.5 eV for N 1 s, 164.4 and 163 eV for S endo and exo-cyclic, respectively. The amount of adsorbed MBT increases from 23 to 32 Å from 1 h to 24 h immersion of copper in the aqueous solution with MBT.

zothiazole (MBT) is studied by XPS. The leaching of zinc (dezincification) is observed in pure water and in borate solutions. On the contrary, if brass is exposed in 0.5 M NaCl or Na 2SO

Aug 1, 2014 · The surface of brass (Cu80/Zn20) exposed in water and different aqueous solutions and 2-mercaptobenzothiazole (MBT) is studied by XPS. The leaching of zinc (dezincification) is observed in pure...

Jan 1, 2014 · X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ions mass spectrometry (ToF-SIMS) analyses were performed to characterize the interaction of Cu with mercaptobenzothiazole (MBT...

It is found that MBT forms multilayers on Cu oxide and inhibits the oxide layer growth. The XPS data are consistent with MBT adsorbed on oxide in multilayers, with a small fraction adsorbed on metallic Cu. These interactions are then further characterized using ToF-SIMS.

Adsorption of 2-mercaptobenzothiazole (2-MBT) at ultra-low pressure and room tempera-ture on metallic and pre-oxidized Cu(111) surfaces and its thermal stability were investi-gated using X-ray photoelectron spectroscopy in order to better understand the interfacial corrosion inhibiting properties. 2-MBT is lying at in the monolayer with two sulphur

Sep 12, 2022 · X-ray photoelectron spectroscopy and time-of-flight secondary ions mass spectrometry analyses were performed to characterize the interaction of Cu with mercaptobenzothiazole (MBT) in aqueous solution without and with NaCl.

The formation of MBT–metal cation complex films on copper and zinc surface has been shown. The effect of corrosive media composition and time-dependent relations of nanoscale film growth on the surface of the metals investigated have been determined.
