Changes in the phase composition of oxide layers produced by microarc oxidation on Al–Si and Mg alloys induced by additions of SiO2 nanoparticles to the electrolyte

详细

In oxide layers produced by microarc oxidation on Al–Si- and Mg-based alloys, addition of nano-dispersed silicon dioxide to the electrolyte was found to cause a shift in the phase composition toward high-temperature phases and ultra-high-pressure phases. For the first time, ultra-high-pressure phases were detected in oxide layers formed by microarc oxidation on AK6M2 alloy (stishovite) and commercially pure magnesium MG96 (wadsleyite).
