Effect of SiO2 Nanoparticles and Soluble Silicate on the Composition and Properties of Oxide Layers Formed by Microarc Oxidizing on Magnesium Mg96

The effect of silica NPs incorporation on protective properties of oxide layers formed by PEO on Mg97Y2Zn1 alloy with LPSO-phase

“…Silicon dioxide in a nanoscale form is one of the most proven substances as an additive to the electrolyte in the PEO of aluminum, magnesium and titanium alloys. It provides a significant increase in the wear resistance and corrosion resistance of oxide layers [ 21 , 25 , [31] , [32] , [33] , [34] , [35] ], is biocompatible [ [36] , [37] , [38] ] and, at the same time, relatively inexpensive. In recent years modifying PEO by adding various ceramic particles to the electrolyte has been widely studied for Mg-alloys such as Mg–Al–Zn, Mg–Mn–Ce and others [ 18 , 21 , 24 , 39 , 40 ].…”
