Abstract
Kinetics of phosphating MA 21 magnesium-lithium alloys in a zinc-nitrate-phosphate solution (0.25 M Zn2++0.34M PO 3−4 +0.17M NO −3 +0.02M F−, pH = 2.7) at 25°C is studied with various surface preparation procedures. The effect of the alloy surface pretreatment in titanium-containing activating solutions on the electrochemical process rate and the initial stage of the phosphate film crystallization is revealed. Peculiarities of the phosphate film growth during different stages of the magnesium-lithium alloy phosphating are elucidated. Combining the activating pretreatment with zinc-phosphate bath allows accelerated applying finegrain thin phosphate conversion layers with enhanced protective effect on magnesium-lithium alloys.
