Electrochemical investigations on the behaviour of Ni-Cr based dental materials in the sodium chloride - oxalic acid - lactic acid system Autori: , Daniel Mareci, Daniel Sutiman, Mircea Teodor NechitaData aparitiei: May/June 2007 Revista: Environmental Engineering and Management Journal › Vol. 6 › Nr. 3 ISSN: 1843 - 3707  Format PDFAbstract
The corrosion behaviour of three commercial nickel-chromium based dental materials was investigated by electrochemical methods in a corroding mixture of sodium chloride, oxalic acid and lactic acid. In order to establish electrochemical parameters of the corrosion process, linear and cyclic polarization curves were plotted. The samples performances in the corroding system were investigated by weight loss, pH and electrical conductivity measurements. The quantitative analysis related with ions released in solution was performed as well. Scanning electron microscopy (SEM) imaging was used for surface investigations. |
