title: Direct preparation of CaTi4 (PO4)6 coatings on the surface of titanium substrate by micro arc oxidation.
abstract: CaTi(4) (PO(4))(6) coatings was prepared on the surface of CP (commercially pure) Titanium substrate via micro arc oxidation in a newly designed electrolyte system. The preparation method -micro arc oxidation, as well as its discharge characterization was described and studied. The phases, morphology, chemical composition of the coatings were characterized by XRD, EDX and SEM analysis respectively. The results show: the main phase of the prepared coating was CaTi(4) (PO(4))(6) which is a bioactive coating material, the morphology of the coating was rather coarse and not like that of traditional MAO coating which was full of pores. Also the samples prepared in different electrolyte systems were studied and compared.
