The electrochemical behaviour of pure nickel in H,S04 solutions has been potentiodynamically investigated. The effects of the following factors on the anodic dissolution and passivation of the metal are discussed: potential scan rate, successive cyclic voltammetry and progressive additions of Cl-, B

## Abstract The behaviour of steels with (%) 17.3 Cr, 5.3 Ni, 0.3โ13.9 Mn during potentiodynamic polarization k tests is comparable to that of 18 8 CrNi steels. Sharp peaks are found in the polarization curves; they correspond to the dissolution of the iron base: This region is followed by a passiv
close to the void fraction that makes intolerable big error in liquid hold-up estimation. In this sense, only limited number of the data were available from Colquhoun-Lee[3] and Specchia[6] because most of their experiments were carried out in high gas and liquid velocity: even their data shown in F
