Summary: | The dependences of the protective properties of the anodic oxide coatings on the AD31 aluminum alloy surface modified with nitrates of magnesium, potassium, and some 3
d
-elements on the composition of sealing solutions and parameters of finishing treatment were established by scanning electron microscopy, potentiodynamic polarization, electrochemical impedance spectroscopy, and salt spray chamber tests. A mechanism of the formation of modified anodic oxide coatings during sealing and subsequent thermal treating was proposed. |
