| Abstract | Oxide coatings on AM60B magnesium alloy were prepared using the microarc oxidation(MA0) technique in silicate-KOH electrolyte with addition of 0-6.0 g/L Na2W04. The MA0 processes in base electrolyte with different concentrations of Na2W04 were studied. The microstructure, compositions and mechanical tribological characteristics of the oxide coatings were also investigated by SEM, XRD, XPS, microhardness analysis and ball-on-disc friction testing, respectively. It is found that the addition of Na2W04 into the base electrolyte has direct effect on the Characteristics of voltage-time curves and breakdown voltage in MA0 process. The number of micropores at top of the coating surface is increased by the addition of Na2W04. The fraction of forsterite Mg2Si04 in the oxide coating increases with increasing concentration of Na2WO4 in base electrolytes. Furthermore, the microhardness and wear resistance of oxide coatings are enhanced as well. |
