STUDY OF CORROSION BEHAVIOR OF AISI304 STAINLESS STEEL SAMPLES USING ACCELERATED ELECTROCHEMICAL METHODS
2016
The aim of this work was the study of corrosion behavior of the AISI304 stainless steel samples in 3%, 6% and 9% acetic acid solutions, using accelarated electrochemical methods. In order to achieve accelerated corrosion tests was been used a system consisting of a potentiostat-galvanostat Wenking HP 96-20, an electrochemical cell, two multimeters Hameg HM 8112-3 for monitoring the voltage values and a PC system for programming, command, acquisition and interpretation of the values recorded on the multimeter. In order to developing the mass balance of the migration process of metal ions were calculated the theoretical masses of 56 Fe, Mn, Cr and Ni ions migrated in the acidic simulant solutions. Chemical analysis of corrosive solutions, after carrying out the electrochemical tests, was carried out using ICP-MS method. Were calculated the dissolution rates η for each metal ion studied. Regarding the corrosion behavior of metal ions in corrosive solutions was observed a decrease of dissolution rate with the increasing of acetic solution concentration.
