Abstract Hydrogen evolution on three sacrifical magnesium anodes AZ63,AZ41 and pure magnesium in fresh water has been studied by means of weight loss,hydrogen collection,electron probe analysis and morphological observation.The results show that all the three magnesium anodes in fresh water are in active state and the velocity of hydrogen evolution os linearly dependent on current density.Their negative differential effect coefficients in fresh water are less than that for magnesium in 0.5mol/L NaCl+Mg(OH)2(pH10.2)solution.Hence the hydrogen evoluton is not the only reason for the low current efficiency of magnesium anodes.The fall of magnesium grains may be the another important cause.

Key words: magnesium sacrificial anode fresh water hydrogen evolution
