| Abstract: | To develop a new technology for deposition of ferroelectric thin film,Ti plates must be microarc oxidated.In this paper,Ti plates were processed by microarc oxidation(MAO) in a series of electrolytes,which were composed of Ba(OH)2,Ba(CH3COO)2,BaCl2,Ba(OH)2+Ba(NO3)2,Pb(CH3COO)2respectively,and the phase composition and morphologies of films were investigated.Results revealed that microarc occurred successfully in Ba(OH)2 and Ba(CH3COO)2 solutions but failed in BaCl2、Pb(CH3COO)2 and Ba(OH)2+Ba(NO3)2 solutions.The film was mainly composed of BaTiO3 phase and scattered with small holes.By comparing the results with different electrolytic,concentrations and currents,a general law for selection of electrolytic compositions and optimal technique was put forward.Dielectric constant of 112 was measured at frequency of 1 kHz. |
