Аннотация

Silicate coatings were deposited on Mg-0.8 wt % Ca alloy by the micro-arc oxidation method at the applied voltages of 350-500 V, in the electrolyte containing wollastonite powder. The coating morphology and elemental composition were studied with the help of the scanning electron microscopy and energy-dispersive X-ray spectroscopy. Elongated crystals similar to wollastonite particles were observed on the coatings surface. The results of elemental analysis confirmed the high content of silicon and calcium in the coatings. After 16-day of the immersion in 0.9% NaCl solution the mass loss was 20% and 5-10% for the bare alloy and for the coatings respectively. Electrochemical studies revealed that the corrosion resistance of the coatings is ten times higher than of the uncoated magnesium alloy.
