  • Title: Corrosion and creep resistance of some dental amalgam alloys.
    Author: Moussa TA, Metwally WA, Habib AN, Abu-Tabl ZM.
    Journal: Egypt Dent J; 1995 Apr; 41(2):1145-57. PubMed ID: 9497651.
    Abstract:
    Corrosion behaviour, creep values and phase transformation of conventional, admixed, unicompositional and two palladium-enriched amalgam alloys were investigated. Weight-loss method and solution analysis for dissolved metal ions were used. Creep values were determined after different immersion periods. X-ray diffraction was carried out to follow up phase transformation after different immersion periods and/or aging in dry air at 37 degrees up to one year. The results have shown that addition of palladium has improved corrosion and creep resistance and reduced gamma 1 to beta 1 phase transformation, and that gamma 2 did not appear again in high copper or palladium-enriched amalgam up to one year.
