Originální abstrakt

Fluoride conversion coating was applied on wrought AZ61 magnesium alloy by the immersion of alloy in Na[BF4] molten salt. Two different temperatures 430 °C and 450 °C, and different treatment times of 0.5; 2 and 8 h were used for the coating preparation. The surface morphology and the cross-sections of the coatings were investigated by scanning electron microscopy, focused ion beam cutting and energy-dispersive X-ray spectroscopy. The electrochemical corrosion characteristics of coated material varied with processing conditions. A significant improvement of electrochemical corrosion properties of the AZ61 magnesium alloy coated with fluoride conversion coatings was revealed by the potentiodynamic tests and electrochemical impedance spectroscopy.
