| Zusammenfassung: | An amalgam capillary-pore electrode with an optically transparent window for in situ viewing is used to screen three dental amalgams for their corrosion resistance. Results are in accord with more extensive clinical findings of decreased corrosion resistance in the order Dispersalloy > NTD > Microalloy. Subsequent examinations by SEM and probe microanalysis show that a preferential corrosion of the poorly resistant Sn-bearing phases involves dissolution of Sn with subsequent diffusion and deposition of a SnO hydrate preferentially on the gamma -1 phase.26 refs.--AA |
