Abstract
The effect of phase composition on corrosion behavior of ternary magne sium-based alloys of the Mg-Y-A1 system under anodic polarization cond itions has been studied. The dissolution rate of the alloys has been s hown to be determined by the character and electrochemical properties of intermetallic phases inherent in the alloys. They affect the activi ty of pitting dissolution of the metal, depending on their characteris tic hydrogen overpotential.
