摘要: Abstract The way of self-healing coating formation at the surface magnesium alloys on base plasma electrolytic oxidation method (PEO) has been suggested. Scanning Vibrating Electrode Technique (SVET) and Ion-Selective (SIET) were used for determining kinetics mechanism process. treatment PEO-layer by solution containing 8-hydroxyquinoline enables one to decrease current density composite in 30 times (3.2 μA cm −2 ) corrosion-active environment comparison with PEO-coating (100 μA cm avert intensive destruction material.
