A STUDY OF FACTORS AFFECTING THE CORROSION RATE OF MAGNESIUM IN VARIOUS ELECTROLYTES UNDER STATIC CONDITIONS

Abstract:

The corrosion rates of magnesium and magnesium alloys in magnesium salt solutions of chloride, bromide, and perchlorate were studied by measuring the gaseous reac tion product as a function of time. Reliable apparatus was developed to accurately determine the volumes of gas generated. Protective films were applied to the surface of the magnesium metal to suppress excessive chemical reactivity at the metal-electrolyte interface, thereby reducing static corrosion rates. Cramolin, one of the films tested, reduced the gas evolution of an AZ21 Mg-2N MgBr2 system from 400 cc800 hrs to 0.1 cc800 hrs.
