Abstract
The electrochemical behavior of magnesium–lithium alloys of MA 21 and IMV 12 types in the solutions of moderately acidic phosphates (0.34 M H3PO4 + 0.17 M HNO3 + NaOH, pH 2.7) containing fluoride ions (0.01–0.09 mol/L)) is studied in the context of phosphating treatment. The relationship of the results of electrochemical studies with the results of phosphating of the given alloys is determined. The dependence of the electrochemical activity of alloys on their nature is shown. The rate of stationary electrochemical process determines the rate of the formation of phosphate films with modified properties and structure on magnesium–lithium alloys.
