potentiodynamic corrosion measurements - Opis:
- In present work, the continuation of general and pitting corrosion analysis of austenitic AISI 316Ti (EN 1.4571) stainless steel in Ringer's solution, is presented. The corrosion was studied by using the ATLAS 98 potentiostat with platinum EPT-101 and calomel reference EK-101P electrodes. The three types of specimens, i.e. as received (without any pretreatment), after abrasive mechanical polishing (MP), and after electrochemical polishing (EP), were used. The best pitting corrosion resistance was recorded for electropolished and passivated (in 20% vol. HNO3 for 30 minutes) surface, i.e. the pitting potential was equal to 761 mVSCE (855.4 ± 58.5 mVSCE), while the worst one was recorded for mechanically ground samples and the pitting corrosion potential was equal to 270 mVSCE (378.8 ± 60.3 mVSCE).
