Повышение износостойкости и коррозионной стойкости оксидных слоёв, формируемых микродуговым оксидированием на алюминиево-кремниевых и магниевых сплавах

Abstract

Has been conducted the experimental analysis of wear resistance and corrosion resistance of oxide layers formed on aluminum alloys 319.0, 361.0, A14130 and on magnesium alloy 9995A with microarc oxidation. Has been observed the improvement of morphology, wear and corrosion resistance of oxide layer with small addition of nanosized silicon dioxide into the electrolyte. Obtained results has showed the advisability of researches of the mechanism of nano-sized particles with electrolytic plasma and growing oxide layer interaction.
