## Abstract The passivity of copper in NaOH and borate buffer solutions containing chloride, bromide and fluoride ions was studied by using cyclic voltammetry and potentiostatic current transient measurements. At scan rates β₯ 20 mVs^β1^, the addition of halide ions does not nearly affect the cyclic

The corrosion and passivation of tin in sodium borate (Na,B,O,) solutions at pH = 8.35 were studied by potentiodynamic and cyclic voltammetry techniques. The effect of the following factors on the anodic dissolution and passivation of tin metal are discussed: concentration of borate ion, pH, potenti
## Abstract The pitting corrosion behaviour of some Ξ±βbrasses (Cu%: 85, 70, 67, 63 and 60) in neutral and alkaline solution containing various halide ions was studied. The pitting corrosion resulted in dezincification in all cases and the pitting potential was found with few exceptions to increase
## Abstract The kinetics of the pit nucleation in iron in borate buffer solution containing bromides and iodides (0.01 nβ0.5 n) has been investigated, and the results have been compared with those obtained for chloride solutions. It has been found that the critical pitting potential, E~cp~, decreas
The pitting corrosion of Al, and two Al-Cu alloys, namely (Al-2.5% Cu) and (Al-7.0% Cu) was investigated in gluconic acid (HG) solution through linear polarization and cyclic voltammetry techniques complemented with ex situ EDX and SEM examinations of the electrode surface. Inductively coupled plasm
## Abstract The passivation behaviour and pitting corrosion of a commercial grade Ξ±βbrass (Cu/Zn:63/37) in neutral buffer solutions (borate and phosphate) in the presence and absence of chloride ions were investigated by electrochemical techniques. The results indicated the dezincification in absen
