In slightly acidic media, the amount of potential shift for all alloys studied is, small as compared to more acid media, pH = 1.85. On the other hand, in alkaline saliva, especially of higher pH, l2.0l, the potential shift for disp-ersallov amalgam, is higher than that of non-precious alloys. Further, Wiron S alloy showed the most resistive alloy in such media. The results of capacitance measurements are in general accord with those implied by the potential. The corrosion potential of the non-precious alloys-amalgam combinations reflect the activity of Wiron S - ama'gam combination and inertness of the other combination. All amalgam samples exhibit a gradual loss of tlie surface iuster with blackish discoloration and pitting after a long exposure period to the medium.  ISSN : 0  Journal Name : Cairo Dental Journal  Volume : 36  Issue Number : 2  Publishing Year : 1990 AH 1990 AD  Article Type : Article  Added Date : Monday, December 10, 2007  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email عصام نجيب Najeeb, esam Investigator Doctorate enajeeb@kau.edu.sa Files File Name Type Description  CORROSION BEHAVIOUR OF DISPERSALLOY.pdf pdf   Back To Researches Page
