Sažetak
In order to simulate the severe corrosion conditions of decreased pH in oral cavity, the present study was undertaken in a solution of artificial saliva with 0.1% lactic acid (LA) added. The corrosive effect of this agent on dental metallic materials has not been well documented. It was an objective of this in vitro study to evaluate electrochemical behavior of ten experimental CoCrMo alloys and compare them to the commercially available dental alloy WIRONIT&reg ; ; . It was shown that LA made the passivation layer on the metallic materials unstable. Some of tested alloys suffered severe pitting attack depending on the microstructure and on Cr-content. The presence of LA in solution significantly decreased E corr- and Eb-potentials.
