Abstract
Svrha ovog rada bila je odrediti optimalne uvijete za proces elektropoliranja austenitnog nehrđajućeg čelika X2CrNiMo17-12-2 (AISI 316L) za primjenu u farmaceutskoj industriji. Ispitivani su utjecaji vremena elektropoliranja, temperature elektrolita, udaljenosti između elektroda i prethodne mehaničke obrade. Uspješnost procesa procjenjivala se mjerenjem korozijske otpornosti tretiranih uzoraka elektrokemijskim metodama Tafelova ekstrapolacija, elektrokemijska impedancijska spektroskopija i linearna polarizacija u otopini NaCl masene koncetracije 3 % te mjerenjem površinske hrapavosti tretiranih uzoraka. Najbolji rezultati dobiveni su pri trajanju procesa od 15 minuta na sobnoj temperaturi za međusobne udaljenosti elektroda od 2 i 4 cm, dok prethodna mehanička obrada nema utjecaja na korozijsku otpornost tretiranog uzorka.
Abstract (english)
The purpose of this paper was to determine the optimal conditions for the electropolishing process of austenitic stainless steel X2CrNiMo17-12-2 (AISI 316L) for application in the pharmaceutical industry. The effects of electropolishing time, electrolyte temperature, distance between electrodes and previous mechanical processing were studied. The success of the process was evaluated by measuring the corrosion resistance of the treated samples by electrochemical methods of Tafel's extrapolation, electrochemical impedance spectroscopy, linear polarization in a 3 % NaCl solution and by measuring the surface roughness of the treated samples. The best results were obtained during the 15-minute process at room temperature for the distance between the electrodes of 2 and 4 cm, whereas the previous mechanical processing did not influence the corrosion resistance of the treated sample.
