Original abstract
Electrochemical charasterics of Mg-3Al-1Zn alloy surfaces after grinding and/or coating by hydroxyapatote were investigated by voltametric tests in 0.9 % NaCl solution. The hydroxyapatite treatments were realised by electrochemical method in water solution of Ca(No3)2.4H2O,(NH4)2HPO4 and H2O2. The influences of various types of hydroxyapatite treatment process on corrosion potentials, corrosion current densites and charasterics of passive state were evaluated. Basic potentiodynamic curves obtained from the electrochemical tests were analysed by Tafel analyses. The improvement of short-time electrochemical behaviour after hydroxyapatite treatment of tested alloy surface was reported.

Elektrochemické charakteristiky na povrchu slitiny Mg-3Al-1Zn po broušení a/nebo s hydroxyapatitovým povlakem byly hodnoceny pomocí voltametrických zkoušek v 0,9 % roztoku NaCl. Hydroxyapatitová vrstva byla vytvořena elektrochemickou metodou ve vodném roztoku Ca(No3)2.4H2O,(NH4)2HPO4 a H2O2. Byl hodnocen vliv různých způsobů výroby hydoxyapatitové vrstvy na korozní potenciál, korozní proud, proudovou hustotu a pasivační charakteristiky.Základní potenciodynamické křivky získáné pomocí elektrochemických testů byly analyzovány Tafelovou analýzou. Bylo zjištěno zlepšení elektrochemického chování materiálu po nanesení hydroxyapatiové vrstvy.
