Abstract
Comparable working conditions and different surface characterization techniques were used to study corrosion behaviour of different materials in different organic solvents. Nickel was investigated with the purpose of studying the evolution of corrosion resistance and the aptitude to passivation as a consequence of water presence. Stability towards stress-corrosion of iron and low-alloyed steel passive films in acid anhydrous environments in the presence of Cl ions and water show the competition between defects nucleation and repassivation of the protective oxide. The electrochemical behaviour of iron and stainless steel in alcoholic solutions of different chain length in the presence of water and Cl ion under controlled fluid-dynamic conditions showed the effects of the chain length related to corrosion resistance and diffusion phenomena.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
