In order to obtain the bioactive ceramic coating,the process condition of the micro-arc oxidation was researched.A suitable formula of electrolyte to prepare bio-modification of titanium by micro-arc oxidation was obtained,which contains Ca(CH3COO)2·H2O 20g/L and Na5P3O10 9.3g/L.The results show that : Using this electrolyte and matching a proper process condition,prepared ceramic coating has porosity structure and combines well with the substrate.The pore distributes equably on the surface of ceramic coati...
