✦ Synopsis

Abstract

The behaviour of Ag‐Sn alloy and Ag‐Sn‐Hg dental amalgam alloy has been studied under potentiostatic conditions in artificial saliva and in sodium chloride solutions containing 0.2% NaCl (alone or mixed with sodium hydrogen phosphate). It has been shown that Sn and Ag as well as the intermetallic compound reveal themselves through maxima in the E/I curves and through the total shift of these curves toward higher currents. The role of γ~2~‐phase in enhancing corrosion and of hydrogen phosphate ions (and of other constituents of saliva) in counteracting the aggressiveness of Cl^−^ ions have been demonstrated.
