Abstract

Multifunctional corrosion resistant and bioactive coatings containing hydroxyapatite Ca₁₀(PO₄)₆(OH)₂ and magnesium oxide MgO were obtained on Mg-Mn-Ce alloy by plasma electrolytic oxidation. The phase and elemental composition, morphology and anticorrosion properties of the coatings were investigated. The PEO layers were post-treated using Forum^® superdispersed polytetrafluoroethylene powder, which caused a considerable reduction of the magnesium alloy corrosion rate (>4 orders of magnitude). In particular, the polarisation resistance has increased, as a result of such duplex treatment, by five orders of magnitude. The composite coatings are considered promising to induce bioactivity and control corrosion degradation of resorbable Mg implants.
