Originální abstrakt

Magnesium materials were classified as biodegradable materials. However, their poor corrosion resistance hinders their widespread use. To increase corrosion resistance, LDH layers can be applied to their surface. In this work, MgAl-LDH layers were produced for the first time on Mg compact prepared by powder metallurgy. The preparation of LDH layers was performed by one-step in situ deposition under optimal conditions for 9 h at 95 °C. The higher deposition time led to a significant increase in the Mg(OH)2 content in the Mg compact and to the occurrence of structural defects. The MgAl-LDH layer had a positive effect on the corrosion properties of Mg compacts in Hank's solution. The corrosion behavior differed in some aspects from conventional Mg materials. The corrosion induced the formation of hydroxyapatite, which initially formed on the LDH layer and improved the corrosion resistance. After the LDH layer was broken, the structural nature of Mg compacts led to intense degradation, which limited the protective effect of corrosion products. Coating thus appears to be a viable and suitable strategy for improving the corrosion properties of Mg materials prepared by powder metallurgy.
