| Abstract: | Effect of K2CrO4 as additive in silicate solution on corrosion resistance of micro-arc oxidation(MAO) coatings on AZ91D magnesium alloys was investigated.Results show that yellow-green coatings containing phases with good corrosion resistance such as MgO,Mg2SiO4,MgAl2O4,and MgCr2O4 were obtained on magnesium alloys processed in silicate solution including K2CrO4 additive.A new phase of MgCr2O4 with spinel structure contributed much to improvement of corrosion resistance of the coatings,and color display was... |
